Title:
POLYMER COMPOSITION CONTAINING OXIDATION-MODIFIABLE CHLORINATED PROPYLENE AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2013/121871
Kind Code:
A1
Abstract:
Provided is a production method with which, by virtue of having a step for chlorinating an oxidation-modifiable propylene-containing polymer using a mixed solvent of chloroform and water, it is possible to produce more efficiently than in the past a polymer composition containing oxidation-modifiable chlorinated propylene that shows little discoloration, contains no polarizing component impurities or low-molecular-weight components, has excellent compatibility with polyurethane resins, and shows excellent adhesion of ink binders containing polyurethane when used for a variety of materials (particularly OPP). At least one polymer containing oxidation-modifiable propylene selected from oxidation-modifiable polypropylene and oxidation-modifiable propylene-α-olefin copolymer is dispersed in a mixture containing chloroform and water and chlorinated at a temperature of 130ºC or lower to obtain a polymer composition containing oxidation-modifiable chlorinated propylene.
