引言乙烯类单体(如苯乙烯、甲基丙烯酸甲脂、丙烯腈)与天然橡胶的接枝共聚研究,早在本世纪的三十一四十年代间已经开始。近十多年来,这一领域的研究工作发展很快,在理论和实际应用上都取得了巨大的成就。然而,过去的工作多偏重于用乙烯类单体对天然橡胶的接枝改性,以得到优异的橡胶制品。由于橡胶链是极为柔软的碳链高聚物,故它可用来对那些硬链的脆性较大的碳链或杂链高聚物进行改性,这样的研究课题量近年来已引起人们极大兴趣。

Introduction The graft copolymerization of ethylene monomers (such as styrene, methyl methacrylate, acrylonitrile) with natural rubber has already begun in the 1930s and 1940s. In recent ten years, the research work in this field has developed rapidly, and great achievements have been made both in theory and in practical application. However, in the past, much work has been devoted to graft modification of natural rubber with vinyl monomers to obtain excellent rubber products. Since rubber chains are extremely soft carbon chain polymers, they can be used to modify carbon chains or heterochain polymers that are more brittle than hard chains, and the amount of research on such issues has been extremely high in recent years interest.
