Abstract RU 2479613 C2

FIELD: chemistry.

SUBSTANCE: polymer type A is a copolyester obtained by cocondensation of unsaturated aliphatic dicarboxylic acids, selected from a group comprising fumaric acid, maleic acid, itaconic acid and esterifiable derivatives thereof, with polyols or lactones. Monomers which form type B polymer are selected from a group comprising methyl(meth)acrylate, ethyl(meth)acrylate, propyl(meth)acrylate, butyl(meth)acrylate and ethylhexyl(meth)acrylate. Type AB polymer is a graft copolymer of type A polymer and type B polymer and is a copolymer with polyester backbone chains and poly(meth)acrylate side chains.

EFFECT: mixture, which contains type A, B and AB polymers, has high compatibility of polymer components and is suitable for use as an adhesive, particularly a melt adhesive.
