The process of rotational foaming molding of liquid reactive resin was studied, with unsaturated polyester resin as the shell of unfoamed resinmoulded part, and polyurethane as foamed core layer.
An unsaturated polyester resin was synthesized from dicyclopentadiene, maleic acid and ethylene glycol. This resin can be moulded by casting and also can be hardened in air.
