Process for the crystallization of high polymers in the presence of nucleant systems based on zeo lites |
摘要 |
The kinetics of crystallization of high polymers from the molten state is modified by adding to the polymers before the thermoforming step low amounts of a nucleating agent consisting of solid particles of crystalline zeolites treated with high-boiling acrylcarboxylic acid or sulphonic acid.
