【摘要】 近年来不饱和聚酯树脂被着眼于利用液体橡胶来增韧,如同增韧环氧树脂所用的方法。遗憾的是液体橡胶增韧不饱和聚酯树脂的效果远不如对环氧树脂的增韧。不少研究者曾在这一领域中进行了研究。本文综述并介绍了可用的液体橡胶的类型,它们的增韧效果和今后发展趋向。更多还原

【Abstract】 Recently unsaturated polyester resin has been focused to be toughend by liquid rubber as the method applied in toughening of epoxy resin.Undesirably the toughening effect of liquid rubber in unsaturated polyester resin is much weaker than in epoxy resin.A number of researchers have done a series of studies in this area.This paper is submitted as a review.It lists the types of available liquid rubber,their toughening effect and discusses the future tendency.更多还原
