NOVEL POLYMERIC HINDERED AMINE LIGHT STABILIZERS BASED ON END FUNCTIONALIZED POLYOLEFINS AND A PROCESS FOR THE PREPARATION THEREOF.

摘要

The present invention relates to a novel end functionalized polypropylene hindered amine light stabilizers. It provides a novel end functionalized polypropylene hindered amine light stabilizers with high functionality of chain ends having hindered amine group. This invention provides a class of PHALS which may be compatible with polyolefins, polystyrene, elastomers and more particularly in fiber applications and can be added in an additive portion to obtain desired photo-stability of various other polymers also. This invention commonly used organic reagents and with high functionality.This compound may be dispersing uniformly in the polymer matrix, when compared to other existed stabilizers because of long hydrophobic chain.
