在反应过程中，存在两大相互竞争的反应．即交联和降解反应。通过对样品一系列性能测试，从中得出一些有价值的结论：聚合物的拉伸强度和凝胶含量随着BPO、TAIC的用量，模压时间和模压温度的提高，出现先升高后降低的规律，且BPO对两者的影响效果最明显。根据实验数据，得出PP交联的最佳方案是：PP 100份，BPO 0.5%，TAIC 1.0%，模压时间9min，模压温度160℃。以此方案制出试样的性能最好。

In the reaction the process, existence two big mutually competition of reaction.namely hand over allied with decline a solution reaction.Pass to the performance test of sample a series, from in get some worthy conclusion:The polymer pull to stretch strength and gel content along with the dosage of the BPO, TAIC, the mold press the exaltation that time and mold press temperature and lower after appearing to go up first of regulation, and the BPO influence both effect most obvious.According to the experiment data, get the PP hand over allied of the best project BE:The PP is 100 and the BPO be 0.5% and the TAIC be 1.0%, the mold press the 9 min in time, and the mold press temperature 160 ℃ .With this project system a the function which try kind had better.

In response process, the existence of two competing responses. That is, cross-linked and degradation. Through a series of sample tests to draw some valuable conclusions: the tensile strength and polymer gel content with the BPO
