Abstract

PURPOSE: To an ethylenic resin are added azodicarbonamide along with a specific organic phosphite ester and a magnesium compound as foaming auxilially agents, thereby utilizing efficiently evolved gases to produce low-density foamed articles.
CONSTITUTION: In the production of foamed articles of ethylenic polymer by using azodicarbonamide as a foaming agent, a phosphite triester bearing 2 or 3 aromatic groups such as diphenyl-2-ethyl hexyl phosphite, and a magnesium compound, such as magnesium oxide are added in amounts of 0.025 part by wt or more per 100 parts of the polymer respectively
