摘要
合成了不饱和聚酯多元醇 ,进而采用化学共混法合成了室温固化的聚氨酯 聚苯乙烯共混物。对其耐热形变性能以及硬度和拉伸强度进行了研究。红外分析结果表明 ,提高反应程度是进一步提高性能的关键。
The room temperature curing polyurethane-polystyrene blends were synthesized with a synthesized unsaturated polyester-polyol by chemical blending method. Its thermal deformation behavior, hardness and tensile strength were determined. The IR analysis showed that raising the reaction extent is the key of further increasing performance.
