摘要: Disclosed is a method of making shaped articles including continuous polyester phase having dispersed therein microbeads cellulose acetate which are at least partially bordered by void space, the being present in an amount about 10-30% weight based on said polyester, space occupying 2-50% volume article. Articles made this have excellent physical properties, especially optical and useful such applications as paper substitutes, for example.
