Preparing chlorinated polyolefin(s) useful in dyes and inks - by mixing polyolefin modified by grafting with unsatd. carboxylic acid and paraffinic hydrocarbon(s)

摘要

Chlorinated polyolefins (I) prepn. comprises mixing a polyolefin or a polyolefin anodified by grafting with unsatd. carboxylic acid and paraffinic hydrocarbons having a carbon number of no less than eight, followed by chlorination to a Cl content of 5-75% at a temp. at which the mixt. remains liq. USE/ADVANTAGE - (I) are used in dyes and inks. They are produced via a simple process and have excellent solubility in organic solvents. The process results in a high yield of chlorinated polyolefins and chlorinated paraffins.
