摘要

研究了在低于常规温度下长时间加热聚合得到的热固化丙烯酸树脂的力学性能。树脂的力学性能低于100℃固化树脂的力学性能。高效液相色谱和差示扫描量热分析结果表明，树脂的力学性能差是由于树脂中残留的大量单体和过氧化苯甲酰，而不是由于分子量的变化。

[Effect of temperature during polymerization on mechanical properties of acrylic resin].

Mechanical properties of heat curing acrylic resin obtained by polymerization for long period of heating at a temperature lower than conventional temperatures were examined. The mechanical properties of the resin were lower than those of the resin cured at 100 degrees C. The results of high performance liquid chromatography and differential scanning calorimetry suggested that the poor mechanical properties were due to significant amounts of residue monomer and benzoyl peroxide in the resin, but is not to changes molecular weight.
