Determination of the Crystallinity of Different Crystalline Forms of Syndiotactic Polystyrene by WAXD
Abstract:
According to the theory of wide angle X-ray diffractometry, the graphic multi-peak resolution results of WAXD patterns of the various crystal forms of syndiotactic polystyrene(sPS)(T', T" and U' forms) were investigated. The correction coefficients of the corresponding crystalline and amorphous diffraction peaks were given and the calculation formulae of the crystallinity of sPS T', T" and U' forms were deduced. The crystallinities of some sPS samples crystallized sufficiently at different temperatures obtained from calculation using the formulae and by DSC experiments were compared to be consistent with each other.
