POLY(DIALLYL PHTHALATE)

Описание

Polydially phthalate (PDP) is prepared from the diallyl 1,3-phthalate [C6 H4 (CH2 —CH=CH2 )]. The linear polymer obtained is a solid thermoplastic still containing unreacted allylic groups spaced at regular intervals along the polymer chain. When mixed with various fillers such as mineral, glass, or synthetic fibers it exhibits good electrical properties under high humidity and high temperature conditions, stable low-loss factors, high surface and volume resistivity, and high arc resistance.
