Dicyclopentadiene dioxide was hardly cured by amines or acid anhydrides alone, but can be well cured by acid anhydrides mixed with alcohols. The curing process using different amounts of maleic anhydride and glycerol were studied, and the influence on gel time and temperature-deformation curve were determined. Although dicyclopenta-diene dioxide is a diepoxide compound, the cured resin formed a more rigid molecular chain, therefore a plastic which shows no glass transition point before the decomposition temperature...

Dicyclopentadiene dioxide was hardly cured by amines or acid anhydrides alone, but can be well cured by acid anhydrides mixed with alcohols. The curing process using different amounts of maleic anhydride and glycerol were studied, and the influence on gel time and temperature-deformation curve were determined. Although dicyclopenta-diene dioxide is a diepoxide compound, the cured resin formed a more rigid molecular chain, therefore a plastic which shows no glass transition point before the decomposition temperature (ca. 300°) may be obtained under optimum amount of curing agent and proper curing conditions.

二氧化双环戊二烯难于被胺或单独的酸酐所固化,但能很好的被酸酐与醇所固化。曾采用不同量的顺丁烯二酸酐及甘油进行固化,并确定了对凝胶时间及温度形变曲綫的影响。二氧化双环戊二烯虽是一种双环氧化合物,但由于能形成较为殭硬的分子链,因此在适当的固化剂用量及固化条件下,能得在分解温度(约300℃)前不出现玻璃化转变的塑料。

The effect of some factors on the graft copolymerization of styrene to polyvinyl alcohol induced by γ-irradiation has been studied, and a preliminary estimation was made on the properties of the graft products. The grafting occured very readily if a proper amount of water was added to the system. It was shown that the rate of grafting increased sharply with the increase of water content in the polymer film and then levelled off, while the rate of homopolymerization increased more slowly and levelled off rapidly at a lower water content. The effect of dose rate on the grafting process at room temperature was studied, and it was found that the grafting was entirely diffusion-controlled with the dose rate larger than 100 r/min, at which the dose rate exponent of the relation V=KIn approached zero. The plot of the amount of grafting with temperature in the range of 10-80℃ passed through a maximum at 60℃ and then fell off, while the homo-polymerization increased steadily all over the temperature range and showed an auto-acceleration at temperatures above 60℃ presumably owing to the gel effect. The presence of oxygen has an inhibiting effect on the grafting. It was found that the homopolymerization could be remarkably inhibited, with only slight reduction in the grafting, by the presence of a proper amount of oxygen or air.The graft product is soluble in dimethylformamide at 150℃. The swelling ratio of the product in boiling water or in boiling benzene was found to change linearly with the grafting. It was also found that the resistance of the film to acid or alkali was significantly improved by the grafting.

本文研究了若干因素对聚乙烯醇与苯乙烯辐射接枝共聚反应的影响,并对接枝产品的性能作了初步鉴定。 在体系里加入适量的水,接枝即甚易发生,此后接枝率先随着聚合物膜片的水含量而急剧增加,然后趋于平坦,而均聚反应速度增加较慢,且在较低的水含量时就不再上升。研究了剂率对接枝过程的影响,发现在常温当所用剂率大于100伦/分时,接枝反应完全受单体扩散控制,此时,接枝速率与剂率的依赖关系式V=KI~n中的n值趋近于零。 在10~80℃范围内,接枝与温度关系的曲线在60℃通过一极大值,然后下降。但均聚反应在整个温度范围内一直随温度而不断地增加,并在温度高于60℃时出现自动加速现象,这大概是凝胶效应的缘故。氧的存在对接枝反应起抑制作用。发现适量氧或空气 的存在可以使均聚反应受到显著抑制,而接枝反应仅略为减慢。接枝产品在沸水或沸苯中的溶胀比与接枝量成线性关系,膜片的抗酸碱性能因接枝而有明显改善。

It has been shown that increasing the temperature of hydrolysis or using a mixed solvent composed of acetone and toluene favours the hydrolytic co-condensation of me-thyltrichlorosilane with phenyltrichlorosilane and dimethyldichlorosilane, but avoids the gel-forming phenomenon. As a result of which a solventless, hydroxyl condensation type silicone resins with lower R/Si, C6H5/E ratio and higher Si-OH group content can be prepared, and the resins are suitable for transfer moulding compounds.

It has been shown that increasing the temperature of hydrolysis or using a mixed solvent composed of acetone and toluene favours the hydrolytic co-condensation of me-thyltrichlorosilane with phenyltrichlorosilane and dimethyldichlorosilane, but avoids the gel-forming phenomenon. As a result of which a solventless, hydroxyl condensation type silicone resins with lower R/Si, C6H5/E ratio and higher Si-OH group content can be prepared, and the resins are suitable for transfer moulding compounds. By using these methods the probedure is simplified, the time of operation is greatly shortened and the quality of the resins is stable.In addition, the relation between the structures of the resins and the properties of the transfer moulding plastics has been discussed. A proper choice of curing agent and a general purpose reinferced filler will result in excellent performance of the plastics.

本文指出提高水解温度,或使用丙酮和甲苯混合溶剂,有利于甲基三氟硅烷与苯基三氯硅烷和二甲基二氯硅烷的共水解缩聚反应,而不易产生凝胶现象。并以此合成了适于递模塑料的R/Si较小、C_6H_5/R较低、羟基含量较高的羟基缩合型无溶剂树脂,简化了步骤,大大缩短了操作时间,树脂质量稳定。此外还讨论了树脂的结构与递模塑料性能的关系,选择了较好的固化剂以及通用的补强剂,使塑料具有优异的性能。
