Vinylidene Chloride Copolymer Particles and Compositions Comprising the Same, and Films and Sheets Obtained from them

摘要

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/vinyl acetate copolymer and an ester of an &agr;,ß−unsaturated carboxylic acid.
