| titleOfInvention | Preparation of chlorinated ethylene copolymer |
| abstract | PURPOSE: To obtain a copolymer having excellent ozone resistance, flame retardancy, heat resistance, wheatherability, mechanical strength and adhesiveness, by bringing at first a specified ethylene copolymer into contact with chlorine in an aq. suspension at a specified temp. to chlorinate the copolymer in part, annealing the mixture at an elevated temp. and then chlorinating the rest. n CONSTITUTION: An ethylene copolymer of an MFR of 0.1W100g/10min is obtd. by copolymerizing ethylene with 0.5W25mol% α,β-unsatd. dicarboxylic acid (or anhydride), etc., [e.g., maleic acid (or anhydride)]. Then, this copolymer is brought into contact with chlorine in an aq. suspension obtd. by suspending this polymer in an aq. medium by using a small amt. of an emulsifier, etc., at a temp. at least 20°C lower than the m.p. of the copolymer and 50°C or higher to chlorinate 20W60% of the copolymer. Then, in the second stage, the temp. is elevated to a temp. 1W10°C higher than the m.p. of the copolymer and annealing is performed without introducing chlorine for 10W60min. In the third stage. chlorination of the rest is carried out at a temp. 2W20°C lower than the m.p. of the copolymer to obtain the title copolymer having a chlorine content of 5W45wt.% and a Mooney viscosity (ML 1+4 , 100°C) of 5 or larger. n COPYRIGHT: (C)1989,JPO&Japio |
