Preparation and Applications of Compatibilizer in HPVC/EPDM

摘要：

The graft copolymer EPDM-g-MMA was synthesized and its compatibilization property for HPVC/EPDM blending materials was studied in this paper. The synthesis conditions were investigated, results showed that the optimum solvent was the mixture of toluene and nheptane with volume ratio of 1:1; the optimum conditions were reaction temperature of 80℃, time of 7 hours, initiator BPO was 0.12％ and monomer MMA was 12％. The synthesis product was characterized by infrared spectroscopy and showed that EPDM-g-MMA grafting copolymer was obtained. The mechanical property of HPVC/EPDM blending materials increased greatly with an increase of compatibilizer content, compared with HPVC/EPDM material with no compatibilizer, when the dosage of EPDM-g-MMA was 9％, the tensile strength of the system increased from 6.8 MPa to 13.65 Mpa, and elongation at break increased from 175.23％ to 347.31％.
