PACKAGE OF SOLID CHLORINATED POLYOLEFIN MODIFIED WITH CARBOXYLIC ACID ANHYDRIDE AND METHOD OF STORING THE SOLID

摘要

The invention provides a package of solid material of carboxylic anhydride-modified chlorinated polyolefin to be used for a binder resin for paint or primer that aims at the protection or beautiful ornament of polyolefinic resins, capable of suppressing the changes in physical properties after storing for a long term, and a method of preserving said solid material. A package of solid material of carboxylic anhydride-modified chlorinated polyolefin, comprising said solid material of carboxylic anhydride-modified chlorinated polyolefin wrapped with a film with the value of water vapor transmission rate measured according to ASTM D895 ("Standard Test Method Water Vapor Permeability of Packages") (measuring conditions: temperature 37.8+/-1.1 DEG C, relative humidity 90+/-2%) of 1.5g/m<2>.24hr or lower, and a method of preserving said solid material.
