| abstract |
Linear, star or dendrimeric block copolymers are composed of from 10 to 90% by weight of at least one block of one or more acrylates of an alcohol of 1 to 8 carbon atoms and from 10 to 90% by weight of at least one block of one or more methacrylates of an alcohol of 1 to 8 carbon atoms, each block having a number average molecular weight of from 1,000 to 100,000 g/mol and the quotient Mw/Mn (weight average/number average) of each block being less than 2, and said block copolymers may be blended with styrene copolymers or acrylate copolymers and, if required, acrylate rubbers. |
