| 1 | 不同硬段含量溶液聚合和RIM嵌段聚脲合成及性质的比较显示文摘用溶液聚合法和RIM合成了软段为胺端基聚环氧丙烷,硬段为4,4′-二苯甲烷二异氰○用二乙基甲苯二胺扩链的热塑性嵌段聚脲。用凝胶渗透色谱和应力-应变研究了这些聚合物的性质。和溶液聚合相比,RIM聚脲有显著的低分子量部分,但二者力学性能差别不大。 | 陈竹生 Willkomm W.R.Macosko C.W. | 1990 | 高分子材料科学与工程1990，6，6： | 11 |
| 2 | 不同硬段含量溶液聚合和RIM嵌段聚脲热性质和动态力学性质的研究显示文摘用溶液聚合法和RIM制备了软段为胺端基聚环氧丙烷,硬段为4,4′-二苯甲烷二异氰酸酯(含量为30%,50%,70%)经二乙基甲苯二胺扩链的热塑性嵌段聚脲。用动态力学温度谱(DMS)和示差扫描量热计法(DSC)对比研究了这些聚脲的性质。结果表明,溶液聚脲比RIM聚脲的枢分离情况好。DMS和DSC均未观察到聚脲中硬段的玻璃化转变。 | 陈竹生 Willkomm W R Macosko C W | 1990 | 高等学校化学学报1990，11，4： | 8 |
| 3 | 不同硬段含量RIM嵌段聚脲成型的研究显示文摘本文研究了软段为胺端基聚环氧丙烷(分子量为2050),硬段为4,4′-二苯甲烷二异氰酯,用二乙基甲苯二胺进行扩链嵌段聚脲的RIM成型。结果表明,硬段含量为30%的RIM浆脲在各种成型条件下都是有韧性的弹性体。硬段含量70%的RIM聚脲在脱模时极脆,在室温下放置,韧性略有增加,但无商业上的应用价值。硬段含量50%的RIM聚脲可以是从极脆到极富韧性的材料,取决于成型温度和脱模时间。较高的成型温度或较长的成型时间,可以得到韧性较好的聚脲。对脱模后聚脲的脆性与存在硬段低聚体有关进行了讨论。 | 陈竹生 Willkomm W.
