METHOD OF INCORPORATING ADDITIVES IN POLYMERIC MATERIALS

摘要

- 24 - 650-6818 METHOD OF INCORPORATING ADDITIVES IN POLYMERIC MATERIALS The incorporation of an additive into a thermoplastic polymer by melt blending can be controlled by incorporating the additive in the form of a cohesive blend with an indicator substance such as an optical brightener, and checking the distribution of the indicator in the final product, e.g. by fluorescence measurements. The presence of a certain quantity of the indicator in a sample ensures the presence of a quantity of additive corresponding to the ratio of additive to indicator in the cohesive blend. 3700/PG/FZ/KC
