Abstract
PURPOSE: To obtain the title foam having improved dimensional stability to hot air, by foaming a styrene-maleic anhydride (M) copolymer with a specific M content, using a specific blowing agent.
CONSTITUTION: A styrene-maleic anhydride (M) copolymer with an M content of 2W25wt% is softened in an extruder, and a hydrocarbon boiling at 5°C or below, e.g. propane or butane, or a halogenated hydrocarbon, e.g. freon -11 or ethyl chloride, as a blowing agent is injected into the copolymer. The resulting composition is foamed and molded under a low pressure and cooled to give the title foam.
EFFECT: Useful as heat insulating material in places at a relatively high temperature up to 100°C.
USE: Backing materials of roofing tiles.
