Abstract

In the present work, the preparation of CPVC carboxylate ionomer is explored. First, a graft copolymer, composed of polyacrylic acid as branched chains and chlorinated polyvinyl chloride as backbone, was synthesized by in-situ chlorinating graft copolymerization. Second, the acid groups of the graft copolymer were neutralized by sodium hydroxide in order to prepare the ionomer. The ionomer was determined by Fourier transform infrared absorption spectrometry, differential scanning calorimetry, dynamic mechanical analysis, and mechanical properties. The results showed that the ionomer was synthesized successfully and its mechanical properties were enhanced notably compared with the graft copolymer.
