Abstract

PURPOSE: An urethane foam that is made by adding lamination chips that has been prepared by laminating a styrene-maleic anhydride copolymer with urethane foams to a urethane foam dope, thus modifying the limpness and deformability and showing relatively high toughness.
CONSTITUTION: Laminated chips that has been perpared by laminating urethane foam with another foam of a copolymer containing at least styrene and maleic anhydride or a blend thereof with other thermoplastic resins, preferably a styrene copolymer containing 2W25wt% of styrene, are admixed to a urehtane foam dope as a filler or reinforcing material. Under stirring, the dope is foamed to produce a reinforced urehtane foam containing the chips.
EFFECT: Since the chips include urehtane foams, the compatibility to the urethane from the dope and adhesion force between them are very high. Thus, the foam is suitably used as a cushioning or package cushioning.
