Stable crystalline structures in solid, - partially crystalline polyolefines

摘要

Stable, crystalline structures in solid, partially crystalline, polyolefines To produce the title materials, 0.01 to 10% w.r.t. weight of polyolefin, of aromatic carboxylic acid amides and/or N-substd. aromatic carboxylic acid imides, are used as nucleating agents, optionally in admixture with other known nucleating substances. The nucleating agent may be pyromellitic acid dianil, with particle size 5 to 20 mu. The nucleating agents give finely crystalline, homogeneous polyolefine compounds.
