Adhesive material based on block copolymers having a p(b)-p(a/c)-p(b) structure

摘要

The invention relates to an adhesive material based on block copolymers of general type P(B)-P(A/C)-P(B). wherein each block copolymer consists of a central copolymer block P(A/C) and terminal polymer block P(B). The invention is characterised in that P(A/C) represents a copolymer from monomers A anid C, which has a glass transition temperature of 0° C.-80° C. wherein component C contains at least one functional group which behaves in an inert manner in a radical polymerisation reaction, and which is used to increase the cohesion of said block copolymer: P(B) represents a polymer from monomers B, which has a glass transition temperature of 20° C.-175° C.; the polymer-block P(B) is insoluble in the copolymer-block P(A/C), and P(A/C) are unmixable.
