POLYMER BLEND

摘要

A polymer blend comprising at least one thermoplastic polymer, cellulosic material and at least one polyisobutylene polymer. The cellulosic material for use in the polymer blend may advantageously be recycled newsprint. Polyisobutylenes are often incorporated into thermoplastic polymers such as polyethelene in the manufacture of stretch or cling wrap films. The blending or recycled newsprint with recycled stretch or cling wrap film produces a useful material from waste products. Advantageously the incorporation of cellulosic material and thermoplastic polymers with polyisobutylene polymers also results in improved dispersion and improved wetting with respect to the cellulosic materials with corresponding improvments in mechanical properties.
