The excess enthalpy relaxation ( EER) process and changes of physical and mechanical properties in a crossly linked unsaturate polyester annealed at temperatures below Tg have been studied. 本文研究了交联不饱和聚酯在低于Tg温度下退火处理,过剩热焓松弛过程及其物理和力学性能的变化。
KGy dose of γ-irradiation decreased content of vitamin B1 significantly and did not had a significant effect on the content of vitamin E, protein, fat, amino acid and unsaturate fatty acid. 4kGy辐照使维生素B1下降31.94%,对维生素E、蛋白、脂肪、氨基酸、不饱和脂肪酸含量无显著影响。
The results showed that the properties of wollastonite/ unsaturate polyester resins composite were improved obviously. 结果表明,改性后的硅灰石可显著改善不饱和聚酯的性能。
