Title:
COMPOSITION OF VINYLIDENE CHLORIDE COPOLYMER PARTICLES
Document Type and Number:
WIPO Patent Application WO/2003/006548
Kind Code:
A1
Abstract:
A composition of vinylidene chloride copolymer particles which, when extruded into a film or sheet, is capable of being stably extruded evenly and which has improved thermal stability. The vinylidene chloride copolymer particles are characterized by having a weight−average particle diameter of 200 to 500 µm and having a content of particles having a particle diameter smaller than 150 µm of 3 wt.% or lower. The vinylidene chloride copolymer composition is characterized by being obtained by compounding the copolymer particles with an ethylene&sol vinyl acetate copolymer and an ester of an &agr ,ß−unsaturated carboxylic acid.
