Abstract:
1. A composition useful for nucleation of polyolefin, comprising: an acetal compound, selected from the group consisting of Bis(4-carboxybenzylidene) pentaerythritol and Bis(4-carboxybenzylidene) dipentaerythritol; an antioxidant, selected from the group consisting of Pentaerythritol Tetrakis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate), Octadecyl 3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate, [4-[4-bis(2,4-ditert-butylphenoxy)phosphanylphenyl]phenyl]-bis(2,4-ditert-butylphenoxy)phosphane and Tris-(2,4-di-tert-butylphenyl)phopshite; an acid scavenger of calcium stearate; and a dispersing agent of petroleum paraffin oil for achievement of nucleation upon dispersal in polyolefin formulations.
