| Abstract: |
| The NR/CPVC thermoplastic vulcanizate (TPV) was prepared by dynamic vulcanization method.The physical properties，solvent resistance and microstructure of NR/CPVC TPV filled with NR-g-(GMA-co-St)/silica were investigated.The results showed that，as the addition level of NR-g-(GMA-co-St) and silica were 7 and 3 phr respectively，the dispersion and uniformity of crosslinked NR as the dispersed phase in CPVC matrix were obviously improved，and the interfacial strength between NR and CPVC was significantly increased.Compared with the unmodified NR/CPVC TPV，the tensile strength，tear strength and elongation at break of NR/CPVC TPV modified by NR-g-(GMA-co-St)/silica were increased，and the solvent resistance was improved. |
