Studies on Miscibility of Polyacetal with Novolak

Abstract

Abstract: The miscibility of polyacetal(POM) with Novolak was studied. It was found that POM/Novolak blends showed a lower critical solution temperature in their cloud point curve and the melting point decreasing by DSCtest. The interaction parameter( χ ) of POMand Novolak was calculated by Hoffman-Week's equilibrium melting point method and Flory equation. The investigation of FTIRfor POM/Novolak blends demonstrated that there was a hydrogen bond between the molecular chain of POMand Novolak, which resulted in the movement of absorption peak to a low frequency. All results certified that POMwas miscible with Novolak.

Key words: POM, Novolak, Interaction parameter, Miscibility
