METHOD FOR PRODUCTION OF MALEINATED PETROLEUM POLYMER RESINS

摘要

polymer production. SUBSTANCE: resins are prepared by interaction of petroleum polymer resin with maleic anhydride at 120-150 C in presence of organoaluminum compounds (diethylaluminum chloride, triethylaluminum chloride) in amounts 1.0 to 3.0 wt %. Resins can be applied in production of drying oils, varnishes and paints, and also as substitute for expensive and scarce colophony in papermaking and as emulsifier in rubber regeneration process. EFFECT: enabled production of resins under mild conditions. 2 tbl, 7 ex
