简介：在聚丙烯(PP)改进硅石的分散矩阵并且避免抗氧化剂的物理损失，有表面(SG-PAMAM)上的dendricpolyamidoamines的nanosilica被使用分叉的方法综合。然后使nanosilica不能调动的抗氧化剂(SG-PAMAM-AO)被从2,6-di-tert-butyl-4-phenol(AO)被导出的grafting2,6-di-tert-butyl-4-aminophenol准备。SG-PAMAM-AO被增加进PP由融化混合学习变老的性质。PP/SG-PAMAM-AO和PP/AO混合物的氧化正式就职时间被测量。SG-PAMAM-AO的抗氧化剂性质比AO的优异，这被发现。根据在相片热的老化前后的羰基吸收的变化，PP/SG-PAMAM-AO的相片热的氧化稳定性比PP，PP/SG-PAMAM和PP/AO的高得多。
