An unsaturated polyester resin composition is provided comprising a hard unsaturated polyester component, a soft unsaturated polyester component and a cross-linking monomer. The soft polyester component contains a polyoxyalkylene segment having a molecular weight from 600 to 6000 in the backbone thereof and is dispersed in the hard polyester component forming fine particles having particle size not greater than 4 microns. The resin composition, when cured, exhibits a Tg corresponding to the hard polyester component from 100°C to 200°C and another Tg corresponding to the soft polyester component from -100°C to 0°C.
一种不饱和聚酯树脂组合物由硬质不饱和聚酯组分、软质不饱和聚酯组分和交联单体组成。软聚酯组分的主链中含有分子量为 600 至 6000 的聚氧亚烷基段,分散在硬聚酯组分中形成粒径不大于 4 微米的细颗粒。固化后的树脂组合物,与硬聚酯组分相对应的 Tg 值为 100°C 至 200°C,与软聚酯组分相对应的另一个 Tg 值为 -100°C 至 0°C。
