Abstract

Graft polymerization of acrylic acid (AA) and acryl amide (AM) onto solid-state chlorinated polyethylene (CPE) has been carried in oil-swellable suspension using benzoyl peroxide (BPO) as an initiator and ethyl acetate (EA) as a sweller. The effects of polymerization conditions on graft degree (GD) and graft efficiency (GE), including volume of sweller, monomer amount, volume of water and reaction time, have been investigated. The graft polymers have been characterized by means of IR. The results show that EA as a sweller, can improve GD obviously, GD of CPE-g-AA is more than 77% when V(EA)/ V(H₂O) = 7/50, GD of CPE-g-AM is more than 96% when V(EA)/V(H₂O) = 8/50. With the increase of monomer amount, GE decreases but GD increases, and GD of mixed monomer is more than that of pure AA or AM monomer.
