Studies on the structures and, mechanical properties of gel and sol in raw rubber state were carried out by employing advanced FTIR mechanical-vibrational spectroscopy and electron computer, More exact and significant results were obtained with the samples strictly prepared and the non-rubber constituents systematically separated. The results srevealed that the composition and content of protein in gel phase were different from those in sol phase. Their rubber chains were also different in structure, particularly in the number of functional groups. Therefore, in gel phase hydrogen bonds were formed between the groups of rubber and protein molecules. Rubber chainss were crosslinked with each other by hydrogen bonds, thus forming a network strucure, The number of functional groups per rubber molecule in gel phase was calculatedby using three novel methods with consistent results. The calculation is of a theoretical significance.

本研究采用先进的傅立叶转换红外光谱及力学——振动光谱手段,并运用电子计算机,研究生胶的凝胶与溶胶的结构及力学性能,由于样品制备严格,并且系统地去除胶样中的非胶组分,所以获得比前人更准确、更深入的结果。本研究结果表明,凝胶与溶胶中的蛋白质的组成与含量有所不同,橡胶烃分子结构亦有差异,主要是分子链上功能基团数目不同。因此,在凝胶中橡胶烃分子与蛋白质分子的基团间形成氢键,橡胶分子通过氢键交联成网状结构。采用3种新颖方法计算的凝胶分子链上功能基团数目的结果基本一致。因此,从理论上来说,本研究具有较大的意义。

Fourier transform infrared (FT-IR)spectroscopy was used to determine the reaction rate of glycidyl dibromophenyl ether(G-48)with methyl tetrahydrophthalic anhydride(THPA) and to compare it with that of the bisphenol-A epoxy resin(E-39)with THPA. The comparison of the reaction rates of the two systems showed that they were noticeably different in various temperature ranges. The apparent energies of activation of the two systems were approximately equal. The curing process of a system composed of a mixture of G-48 and E-39 with THPA as curing agent also was studied by FT-IR. It has been found that the curing behavior of G-48/E-39 with THPA matched the reaction characteristics of the combination of E-39 and G-48 reacting alone with THPA. The curing mechanism of G-48/E-39 mixture system with THPA was proposed.
