Abstract
PURPOSE: To provide a titled composition which consists in compounding two kinds of crosslinking agents and polymerization catalysts such as styrene monomer to unsaturated polyester which is low in viscosity at above its softening point and is not virtually tacky at ordinary temp. and which is not tacky and has high cross-linking reactivity at the molding and firing.
CONSTITUTION: Particularly crystalline unsaturated polyester (component A) which is solid at ordinary temp. and is ≤500 poise and particularly ≤100 poise from the softening point up to 30°C and over is prepared. Next, 10W50pts.wt. a cross-linking agent comprising 5W40pts.wt. styrene monomer and allyphthalate for the remainder and 0.1W10pts.wt. polymerization catalyst (e.g.: bonzoyl peroxide) are added and mixed to 100pts.wt. this component A, whereby the intended resin composition for binding of molding sand grains is obtained. Here, the component A is produced by subjecting, for example, fumaric acid, phthalic anhydride and glycols to esterification condensation reaction by conventional methods. In addition, the titled composition is used at the time of forming mold and cores for castings.
