  An unsaturated polyester resin is toughened by reacting into its backbone an epoxy-terminated reactive liquid polymer (epoxy-RLP). The epoxy-RLP can be a difunctional epoxy-RLP or a reaction product statistical monofunctional epoxy-RLP or a blended product statistical monofunctional epoxy-RLP. The reactive liquid polymer has a carbon-carbon backbone typically containing polymerized units of at least one vinylidene monomer having at least one terminal CH₂=C〈 group, preferably a copolymer backbone of 1,3-butadiene/acrylonitrile. The modified unsaturated polyester is prepared by co-reacting the epoxy-RLP with the reactants of the unsaturated polyester resin by conventional means. The inventive resins have improved fracture energy toughness over unmodified unsaturated polyester resins.

  不饱和聚酯树脂通过与环氧封端活性液态聚合物（环氧-RLP）在其主干上发生反应而得到增韧。环氧-RLP 可以是双官能团环氧-RLP 或统计单官能团环氧-RLP 的反应产物或统计单官能团环氧-RLP 的混合产物。反应性液体聚合物具有碳-碳骨架，通常含有至少一种亚乙烯基单体的聚合单元，该单体具有至少一个末端 CH₂=C〈基团，最好是 1,3-丁二烯/丙烯腈共聚物骨架。改性不饱和聚酯是通过常规方法将环氧-RLP 与不饱和聚酯树脂的反应物共同反应制备的。与未改性的不饱和聚酯树脂相比，本发明的树脂具有更好的断裂能韧性。

  Unsaturated polyester resins of the type already having reactive liquid polymers reacted into the backbone of the resins, are cured in the presence of a reactive liquid polymer additive admixed with the prereacted unsaturated polyester resin. Heating of this system during cure causes the reactive liquid polymer additive to miscibilize with the unsaturated polyester resin. The unsaturated polyester resin modified in the manner described above shows a significant enhancement in toughness as measured by fracture energy over unmodified counterparts or counterparts modified by known methods of adduction or admixing alone.

  已将反应性液态聚合物反应到树脂骨架中的不饱和聚酯树脂，在反应性液态聚合物添加剂与预先反应的不饱和聚酯树脂混合的情况下固化。在固化过程中加热该系统，可使活性液态聚合物添加剂与不饱和聚酯树脂混溶。按上述方法改性的不饱和聚酯树脂，与未改性的同类产品或仅用已知的加成或掺合方法改性的同类产品相比，通过断裂能测量，其韧性显著提高。
