FIELD: polymers.
SUBSTANCE: invention describes highly transparent composition consisting of the following components: (1) from 30% to 95% of polystyrene; (2) from 70% to 5% of composition of block-copolymers of vinylarene and coupled diene wherein percent sum of (1) and (2) is 100. The composition (2) consists of: (2a) from 30 wt.-% to 60 wt.-% of copolymers of linear structure; (2b) from 70 wt.-% to 40 wt.-% of copolymers of branched structure. An average mass molecular mass of above described composition (2) is in the range from 30 000 to 400 000 Da. Invention provides the development of highly transparent composition with retained mechanical properties.
EFFECT: valuable properties of composition.
