The Methylcyclohexane is substituted for the heptane used in the standard test procedure. Unpublished Title of application: The use of Escorez LC gives a better high temperature shear to steel like 5 found for Piccotac 95E but also gives the highest viscosity. The main request is therefore not allowable. The catalyst for the polymerization is used in an 10 amount of 1.Īromatic modified tackifying resins, however, are disadvantageous for a number of reasons.
The claimed process was therefore obvious from D29 alone or in combination with D Try out new Espacenet Tell us what you think. The reaction time is typically from about 1. To determine the Gardner color the resin was mixed with reagent grade toluene at room temperature until all the resin was dissolved. A hot melt pressure sensitive adhesive composition comprising a mixture of: Method for the determination of the SAFT: The resins of esxorez present invention are particularly distinguished from aliphatic resins of the state of the art in that they contain a higher amount of cyclic structures. The priority date 15 December is therefore not validly claimed.Įcorez D29 is representative of the closest prior art. What we claim is: The hot melt pressure esckrez adhesive composition according to claim 7 which contains about esscorez to about parts by weight of a petroleum-based aliphatic resin, about parts by weight of a polymer and about 0 to about 70 parts by weight of an extender oil. 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.
