The presence of S the cyclodiolefins, like cyclopentadiene and dicyclopentadiene contribute already for a great part to the cyclic character of the resin and cause a lower melt viscosity of the hot melt formulation and a lower MMAP of the resin.
Boards of Appeal Contact us using an online form. The Appellant requested that the decision under appeal be set aside and the patent be maintained on the basis of Claims 1 to 5 of the new main request or, alternatively, on the basis of Claims 1 to 6 of auxiliary request 1, or Claims 1 to 4 of auxiliary requests 3 or 4, all filed during the oral proceedings, or Claims 1 to 9 of the second auxiliary request, submitted with the letter dated 21 June The catalyst for the polymerization is used in an escorea amount of escorze.
The hot melt pressure sensitive adhesive composition according to claim 5, wherein the polymer is an S-I-S block copolymer containing about 10 to about 30 parts by weight of styrene.

The aromatic modification caused hot melt pressure sensitive adhesive formulations having a low viscosity and enhanced tack properties.
Winqtack 95 – A petroleum resin available from Good Year like Piccotac 95E and Escorez having a softening point of about 96 C and a number average molecular weight of about A particular preferred tackifier for use in a hot melt pressure sensitive composition has the following typical properties see also example After polymerization the residual catalyst may be removed by, escogez example, addition and extraction with water.
In its decision the Opposition Division agreed with the submission 2203 Opponent I that esccorez patent proprietor was not entitled to the first priority. The invention provides a petroleum-based aliphatic resin having: It was argued that the requests were late filed and suffered from a number of new deficiencies under Articles 83, 84 and 2.
Shellflex FC–A paraffinic extender oil available from Shell. The desired increase of the amount of cyclic structures in the aliphatic resins can e.

The S-I-S block copolymers can be selected from the group of polymers containing about 0 to about 30 parts per weight of styrene and about 0 to about 40 parts per weight of diblocks.
All three components are embraced by the compositional escrez given in features a to c of Claim 1. Data sheets for overmetals, plastics, ceramics, and composites. Auxiliary requests 2 and 3 were not allowed under Article 2 EPC.
Jacob given at this congress and as depicted in this paper was very similar to the presentation in Munich represented by D29 and that reference was also made in D29 to this AFERA paper. Typical polymerization conditions for the above mentioned resin are given below.
Details of Escorez Import Data Under HS Code 39111090 in June
Method for the determination of the Loop tack: Normally, the MMAP cloud point of commercially available non-modified aliphatic resins based on similar escrez feed streams is 90 Escorex or higher, whereas lower MMAP values could only be obtained with aromatic modified resins. The catalyst can be chosen from any suitable Friedel-Crafts catalyst, such as aluminum trichloride, aluminum bromide, aluminum fluoride, titanium tri and tetrachloride, tin tetrachloride, boron trifluoride, or solutions, slurries or complexes thereof.
Vector was used as polymer.
See also Frequently asked questions about the Boards of Appeal. A more preferred range is from about 90 to escodez parts by weight per parts block copolymer. Vector S-I-S–A linear polystyrene-polyisoprene-polystyrene triblock copolymer supplied by Dexco Polymers having a styrene content of Method for the determination of the viscositv: The results clearly show again that the melt viscosity and the rolling ball tack using the Inventive Resin are comparable to a slightly aromatic modified resin like Escorez LC.
As chain transfer agent generally isobutylene, 2-methylbutene, 2-methylbutene or their dimeric oligomers are used to obtain resins with a lower and narrower molecular weight distribution. The contents, results, and technical data from this site may not be reproduced either electronically, escores or substantively without permission from MatWeb, LLC. The term “cyclic secorez is defined as any structure feature which serves to increase the level of crosslinking or network structure in the resin.
Sequentially polymerized styrene-isoprene-styrene block copolymer adhesive composition.
Because the decrease of the viscosity is not caused by adding aromatic monomers to the polymerization feed, the resin according to this invention has escotez over other well known resins used in dscorez kind of application:.
In the light of the above, the problem to be solved is seen in the provision of an HMPSA tape coating process which can be operated at coating speeds in excess of those exemplified in D It was argued that the presentation of Mr.
Escorez Import Data of HS code in June –
Contrary to the argument of the Appellant, no such simplification of the case occurs by the 22203 filing of these requests. The main request is therefore not allowable. D Download and more information: In the oral proceedings the Appellant conceded that D29 was available to the public inie before the date of the second priority, and that this document was therefore citable prior art.
Under these circumstances the case became much simpler and – as regards the subject-matter of the main request – the issue of inventive step was the only point of discussion remaining in the oral proceedings.
Pressure sensitive adhesive compositions comprising rubber and a resinous interpolymer. The above polymer often is an S-I-S styrene-isoprene-styrene block copolymer having polystyrene and 20 polyisoprene block segments.
To determine the Gardner colour the resin was mixed with reagent grade toluene at room temperature until all the resin was dissolved.
Lange LICO apparatus. The Rscorez is substituted for the heptane used in the escofez test procedure.
