Abstract:

A package of a carboxylic-acid-anhydride-modified solid chlorinated polyolefin for use as a binder resin for coating compositions or primers. It is intended to protect or beautifully package the polyolefin resin. It is effective in inhibiting the resin from suffering a change in material properties through long-term storage. The package comprises a carboxylic-acid-anhydride-modified solid chlorinated polyolefin and a film with which the polyolefin is covered, the film having a water vapor permeability of 1.5 g/m?2¿ 24 hr or lower as measured in accordance with ASTM D895 ('Standard Test Method Water Vapor Permeability of Packages') (measurement conditions: temperature, 37.8±1.1°C; relative humidity, 90±2%).
