<p>The polymer composition includes, in %: 1) from 30 to 95 polystyrene , and 2) from 70 to 5 composition of block copolymers of vinyl and conjugated diene. The sum of the percentages of 1) & 2) is equal to 100. Composition 2) consists of the following components, in wt. %: 2a) from 30 to 60 copolymers of linear structure, and 2b) from 70 to 40 copolymers with a branching structure. The mean weight molecular mass of composition 2) is from 30,000 to 400,000, and best from 50,000 to 200,000.</p> |
