Abstract

PURPOSE: The titled molded article useful for covering pipes, rods, etc., having improved heat resistance, flexibility, and adhesiveness, obtained by reacting a specific rubbery polymer with an epoxy resin, blending the reaction product with a blowing agent and a curing agent to give a composition which is molded into a rod shape.
CONSTITUTION: (A) An epoxy resin (preferably bisphenol type, etc. solid at normal temperature) is reacted with (B) 20W70wt%, preferably 35W60wt% carboxyl group-containing rubbery polymer liquid at normal temperature [preferably molecular weight 3,000W4,000, number of COOH group 1.8W2.4 (per mole), having COOH groups in the both ends of the molecule, for example, COOH group- containing acrylonitrile-butadiene copolymer, etc.]. A curing agent, e.g., acid anhydride, etc. and a blowing agent, e.g., an azo compound, etc. to the reaction product to give a composition, which is molded into a rod shape. If necessary, the molded article is drawn to 1.5W3 times, and it is provided with heat shrinkability, to give a pipe having improved adhesiveness.
