摘要:
Disclosed is a clarifying composition mainly containing a phosphonite stabilizer composition, the main component of which is tetrakis-(2,4-di-tert-butylphenyl)-4,4-biphenylene diphosphite, with certain sorbitol based compounds having a melting point of greater than 200.degree. C., a process for preparing the clarifying compositions and polyolefin compositions containing the clarifying composition.
摘要:
The present subject matter relates generally to polymer compositions, and more particularly to irradiated polymer compositions comprising at least one non-phenolic stabilizer. The present polymer compositions comprise an unexpected balance of properties after being subjected to irradiation treatments, including an unexpected combination of a lower melt flow rate ratio (MFRr) and high melt tension after being irradiated, while minimizing negative yellowing effects.
