Abstract: |
The influence of HCCP(high chlorine content polymer)such as PVC,CPE,CLR and CPVC on MMA(methyl methacrylate)/CR graft copolymerization was investigated.The results showed that HCCP accelerated the reaction rate and increased the graft efficiency;as the β-H amount in HCCP increased,the reaction rate speeded up in the order of PVC>CPE>CLR>CPVC;the tensile strength,tear strength and adhesion of the graft copolymer improved significantly by adding HCCP in copolymerization. |
