Document Type and Number:
Japanese Patent JP2004509202
Kind Code:
A
Abstract:
Disclosed is a transparent polymeric blend, which is readily recyclable several times without any significant deterioration in clarity or transparency of articles produced therefrom, comprising: A) from 9 to 90 parts by weight, preferably from 15 to 75 parts by weight, of a monovinyl aromatic-conjugated dine copolymer having a weight average molecular weight (Mw) from 50,000 to 400,000; B) from 9 to 90 parts by weight, preferably from 15 to 75 parts by weight, of a monovinylidene aromatic polymer having a weight average molecular weight (Mw) from 50,000 to 400,000; and C) from 1 to 60 parts by weight, preferably from 2 to 50 parts by weight, more preferably from 3 to 40 parts by weight, of a styrene-isoprene-styrene triblock copolymer having a weight average molecular weight of from about 40,000 to about 150,000 wherein the styrene content is from about 25 to 60 weight percent of the total polymer, and the sum of A), B) and C) being 100 parts. Also disclosed are shaped articles made from such blend and process for preparing such articles.
