Abstract

PURPOSE: To prepare a blowing agent giving colorless, uniform, finely divided foam having comfortable touch, by adding an antioxidant to a mixture of azodicarbonamide and dinitrosopentamethylenetetramine.
CONSTITUTION: A composition composed of (A) 100 parts by weight of a mixture consisting of (a) 100 parts of azodicarbonamide and (b) 3W30 parts, pref. 5W15 parts of dinitrosopentamethylenetetramine, and (B) 0.5W10 parts by weight of an antioxidant such as octadecyl-3-(3,5-di-t-butyl-4-hydroxyphenyl)-propionate, distearyl-3,3'-thiodipropionate, etc.
EFFECT: A thermoplastic resin foam having high expansion ratio can be stably prepared.
