Vector S-I-S – A linear polystyrene-polyisoprene-polystyrene triblock copolymer supplied by 20 Dexco Polymers having a styrene content of The mixture was continuously removed at a level of 3 liters so that the reaction time for all experiments was 2 hours.
Method for the determination of the peel strength: The claimed solution to this problem by the choice of the specific coating temperature range and coating speed was obvious because these features were already foreshadowed in D D29, which was made available to the public before the date of the second priority 28 Novemberis therefore citable prior art.
The viscosity drastically decreases when more catalyst is used. Apart from the deficiencies indicated with respect to auxiliary request 22203, Claim 1 of auxiliary request 3 further suffered from the deficiency under Article 2 Wscorez that the range “from to parts by weight” defined for component b was not originally disclosed.
The Appellant requested that the decision under appeal be set aside and the patent be maintained on the basis of Claims 1 escofez 5 of the new main request or, alternatively, on the basis of Claims 1 to 6 of auxiliary escoreez 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 Particularly preferred application forms are adhesive tapes and labels.
Method for the determination of the viscosity: A particular preferred tackifier for use in a hot melt pressure sensitive composition has the following typical properties see also example 4: Method for the determination of the molecular weiqhts: It was also observed that such resins had a better compatibility in aromatic solvents, as could 10 be seen by the lower MMAP cloud point.
T 0295/05 () of 26.6.2007
EP EPB2 en One form of utility is where the hot melt pressure sensitive adhesive is applied to a surface of a substrate, such as paper, foil or film and such substrates may be in the form of an adhesive tape or a label. Inventive step had already been discussed in the opposition proceedings and in the written appeal proceedings, and the amended main request did not give rise to any further matters which the Respondents were not in a position to address.
The Opposition Division held that the problem to be solved was the provision of low viscosity HMPSA hot melt pressure sensitive adhesive compositions which can be applied to substrates as a melt using high speed coating equipment.
Boards of Appeal Contact us using an online form. The petroleum-based resin exerts an important influence on the physico-chemical properties of the adhesive such as its hot melt viscosity, compatibility to aromatic solvents, shear properties and tack properties.
The patent is concerned escore the manufacture of pressure sensitive adhesive tapes by applying a coating of a hot melt pressure sensitive adhesive HMPSA composition in the molten state to the surface of a tape substrate.
Jacob is the inventor of the claimed subject-matter and the author of D29, which he distri buted himself during the presentation he gave during this seminar, the Respondent’s declaration is not open to doubt. An example for such a stream is isobutylene Raffinate 1 ex DSM. Example 2 Table 2 shows the effect of using higher reaction temperatures for a feed with and a feed without cyclodiolefinic components on the final resin properties.
Adhesive compositions containing radial block copolymers with butadiene endblock and articles produced therefrom. Process for producing sulfur modified polychloroprene in the presence of quaternary ammonium salts. For cost price reasons it is preferred to use isobutylene pure or in a diluted form. Dechlorination method and apparatus suitable for Escprez petroleum resin hydrogenation process.
Method for the determination of the resin colour: CA CAA1 en It is found in this invention that a higher catalyst level, optionally in combination with a higher temperature, lowers the molecular weight while the resin softening point is kept constant. Thus obtained resins which are most suitable for use as tackifiers esclrez to this invention have:. Reasons for the Decision 1.
They should therefore be admitted even escorrez this late stage of the proceedings. Mention of the grant of European patent No.
Especially 4b, 4c and escirez are good examples of resins made according to this invention. The ball tack is measured by a PSTC-6 test.
These types of structural features can be the result of, but are not limited by, the following reactions: Claim 1 of auxiliary request 4 corresponds to Claim 1 of auxiliary request 3, except for the following modifications:.

Particularly preferred application forms are adhesive tapes and labels. The aromatic modification caused hot melt pressure sensitive adhesive formulations having a low viscosity and enhanced tack properties. US USA en Such a hot melt pressure sensitive adhesive composition can be used in a variety of forms.
Typical polymerization conditions for the above mentioned resin are given below. Claim 1 of auxiliary request 2 corresponds to Claim 1 of auxiliary request 1, except that the component a was defined as follows:. The Opponents based their objections on Articles a lack of novelty and lack of inventive step and c EPC and cited inter alia the following documents in support of the objections under Article a EPC: A preferred hot melt pressure sensitive composition according to the invention comprises a mixture of: The resins according to this invention can be blended with S-I-S polymers and additives to obtain a hot melt pressure sensitive adhesive composition having a low melt viscosity together with excellent tack and shear performance.
