ALPHA-METHYLENE LACTONE HOMOPOLYMER AND COPOLYMER COMPOSITIONS, SHEETS AND ARTICLES MADE THEREFROM AND THE PROCESS FOR THEIR MANUFACTURE

摘要

Compositions comprising homopolymers or copolymers containing repeat units derived from alpha -methylene-lact(ones)(ams) such as alpha -methylenebutyrolactones and an inorganic filler such as alumina trihydrate are described. The decorative sheets and articles made from these compositions may have one or more of higher thermal resistance, higher hardness, higher scratch and mar resistance, faster polymerization rates, antimicrobial properties, lower coefficient of thermal expansion and, owing to a higher refractive index, a higher transparency.
