MANUFACTURING METHOD OF PETROLEUM RESIN-GRAFTED POLYAMIDE CAPABLE OF INCREASING ADHESION OF A NEW DIMER ACID BASED ADHESIVE AND REDUCING COST

摘要

PURPOSE: A manufacturing method of polyamide resin is provided to manufacture a graft polyamide resin with improved fracture elongation and tensile strength by grafting petroleum to a polyamide backbone.;CONSTITUTION: A manufacturing method of polyamide resin comprises: a step of manufacturing a maleic petroleum resin through a reaction between a double bond of a petroleum resin and a double bond of maleic anhydride by reacting the petroleum resin and the maleic anhydride in a reactor; and a step of graft polymerization of the petroleum resin through an imide-forming reaction by putting polyamide into the maleic petroleum resin. For the reaction between a double bond of the petroleum resin and the double bond of the maleic anhydride resin, dicumyl peroxide is used as a radical polymerization initiator.;COPYRIGHT KIPO 2013;[Reference numerals] (AA) Polyamide graftomer
