Abstract

PURPOSE: To obtain a foamed body pertinent in heat resistive size stability by a method wherein copolymer of styrene-maleic anhydride is formed by foaming utilizing a low boiling point foaming agent such as methyl chloride or propane.
CONSTITUTION: In case a foaming body is obtained from styrene serise resin, styrene-maleic anhydride copolymer, in which 2W25wt% of maleic anhydride is copolymerized with another styrene, is utilized as the resin, and a mixture, being occupied with 50wt% of methyl chloride and the balance wt% of hydrocarbon having a boiling point of 20° or less or a harogenized hydrocarbon, is utilized as a foaming agent. The foaming agent is forcibly injected into the copolymerized body and the copolymerized body is heated to be softened and foamed, thereby, a styrene series resin foamed body pertinent in size stability may be obtained.
