Abstract

PURPOSE: A chroman derivative, 2,6-di-t-butyl-p-cresol and an imidazole are incorporated to a thermoplastic polymer to prevent yellowing of the resin composition during heat forming.
CONSTITUTION: To (A) 100 parts by wt of a thermoplastic polymer such as from α-olefin of 10 or less carbon atoms, are incorporated preferably under nitrogen atmosphere (B) 0.005W0.5, preferably 0.01W0.2 part of a chroman derivative of the formula (R1 is hydrocarbyl of 1-16 carbon atoms; R2W7, R9, R10 are H, alkyl of 1-7 carbon atoms; R8 is group containing O, S, P and/or N) such as tocopherol, (C) 0.5 or less part of 2,6-di-t-butyl-p-cresol and (D) 0.005W0.5, preferably 0.01 W0.2 part of an imidazole analog, preferably 2-undecanylimidazole
