Abstract
The crystallization of the alpha- and beta-form crystals of syndiotactic po lystyrene (sPS) is determined by the crystallization temperature. Being cry stallized at various temperatures from the melt, sPS forms the beta form cr ystal at high temperatures above about 230 degrees C, alpha form crystal at law temperatures below about 170 degrees C and a mixture of the alpha and beta form at intermediate temperatures.
