用少量合成橡胶与聚苯乙烯混炼进行机械-化学接枝共聚或以少量天然橡胶与苯乙烯接枝共聚都得到了耐热性好、抗冲击强度较高的聚苯乙烯.在这里我们试图在少量天然橡胶与苯乙烯接枝共聚时引入适量的甲基丙烯酸,使得到的接枝共聚物中含有甲
With a small amount of synthetic rubber and polystyrene mixing for mechanical - chemical graft copolymerization or a small amount of natural rubber and styrene graft copolymerization have been good heat resistance, high impact strength polystyrene. Here we try A small amount of natural rubber and styrene grafted copolymerization appropriate amount of methacrylic acid, so that the resulting graft copolymer containing a
