Abstract

${\alpha},{\omega}$-Hydroxypropylpoly(dimethylsiloxane) was prepared from the reaction of a ${\alpha},{\omega}$-hydrogen polydimethylsiloxane with an allyl alcohol. MPE-g-poly(dimethylsiloxane) copolymer (MPES) was prepared from the graft copolymerization of MPE with ${\alpha},{\omega}$-hydroxypropyl group terminated PDMS. MPES/HDPE/EtO-CNT need to varify was prepared from the compounding of MPES, HDPE, and surface treated MWCNT with 4-ethoxybenzoic acid at $180^{\circ}C$. Melting point of the MPES/HDPE/EtO-CNT composite was decreased from 130 to $129^{\circ}C$ as increasing the content of MWCNT 10 to 20 wt% in the composite PTC characteristic of the MPES/HDPE/EtO-CNT composite was appeared at $120^{\circ}C$ as abruptly increasing the electrical resistivity at this temperature. The heighest PTC intensity of MPES/HDPE/EtO-CNT compsite at 10 wt% loading of EtO-CNT was 1.9.
