    • The present invention relates to the use of alkoxylated phosphate esters as internal mold release agents and/or viscosity modifiers in polyester resin compositions, plastic parts comprising such resin compositions and methods of manufacturing said plastic parts. The alkoxylated phosphate esters disclosed herein are virtually free of acid and are capable of functioning as both internal mold release agents and viscosity modifiers in filled polyester resin systems. Additionally, the use of the alkoxylated phosphate esters in accordance with the instant invention provides for dramatically reduced corrosion of metal parts (e.g., a metal mold) which come in contact with the resin compositions during production of thermoset composites. The instant invention further relates to a process for preparing pultruded parts utilizing said alkoxylated phosphate esters. The alkoxylated phosphate esters generally display excellent viscosity reduction properties without the use of chlorinated solvents or styrene diluents associated with conventional polyester resin viscosity reducing agents.
    • 本发明涉及在聚酯树脂组合物中使用烷氧基化磷酸酯作为内部脱模剂和/或粘度调节剂,包含这种树脂组合物的塑料部件和制造所述塑料部件的方法。 本文公开的烷氧基化磷酸酯基本上不含酸,并且能够用作填充聚酯树脂体系中的内部脱模剂和粘度调节剂。 此外,根据本发明的烷氧基化磷酸酯的使用提供了在制备热固性复合材料期间与树脂组合物接触的金属部件(例如,金属模具)的显着降低的腐蚀。 本发明还涉及使用所述烷氧基化磷酸酯制备拉挤部件的方法。 烷氧基化磷酸酯通常显示出优异的降粘性能,而不使用与常规聚酯树脂粘度降低剂相关的氯化溶剂或苯乙烯稀释剂。
