离聚体的拉伸强度、搭接剪切强度和乳化性能均随顺酐化程度的提高而改善。
Tensile strength and lap shear strength increased with increasing of grafting degree due to great improvement of polarity.
研究结果表明： 防热涂料的剪切强度分散性较大，这主要是由于溢胶现象使得搭接长度的准确测量比较困难，同时造成了试件的对中性较差。
The results show that the data of shear strength are discrete. The main factor is the overflow dope that causes the lap length to be measured difficultly and the centerline disagree.
