황화 나트륨(나2S)과의 1,4-디클로로벤젠 중합체

황화 나트륨(나2S)과의 1,4-디클로로벤젠 중합체 화학적 특성, 용도, 생산

• 화학적 성질

  Poly(phenylene sulphide) is a strong, stiff although somewhat brittle material. Mouldings are generally processed so as to be crystalline; since the glass-transition temperature is high (Tg = 90°C), heated moulds are used. The outstanding characteristic of the polymer is its thermal stability, useful mechanical properties being retained up to about 250°C. Electrical insulation characteristics are also good. The polymer has excellent solvent resistance, being unaffected by all common organic solvents. The polymer is resistant to most acids and alkalis, although it is attacked by concentrated sulphuric acid. Poly(phenylene sulphide) is mostly processed by injection moulding and is used in a variety of applications such as electrical components, automotive parts and processing equipment exposed to corrosive environments.

• 제조 방법

  Poly(p-phenylene sulphide) (commonly called poly(phenylene sulphide) or PPS) is the sulphur analogue of poly(p-phenylene oxide) and is prepared from p-dichloroben:lene and sodium sulphide:
