DIALKYL DICARBONATES AS BLOWING AGENTS FOR POLYMERS

摘要

AM5444 The present invention pertains to a composition of matter and to a method of using the composition to produce foamed plastics, wherein a major, auxiliary source of blowing agent for the foam is the decomposition of dialkyl dicarbonates. The dialkyl dicarbonates can be decomposed over temperatures ranging from about 10.degree.C to about 45.degree.C when used in combination with particular tertiary amine decomposition catalysts.
