某些乙烯基类单体,在一定条件下,可以与许多天然高分子化合物(如橡胶、纤维素、羊毛、酪索、皮革等)发生接枝共聚反应,生成接枝共聚物。这类接枝共聚物一般能兼具天然高分子和单体均聚物的特性,因此接枝共聚已广泛用于天然高分子化合物的改性。胶原是生物机体组织(如皮、骨、结缔组织等)的重要成分。胶原与各种乙烯基类单体的接枝共聚,近年来国外已有不少报导。不同单体对胶原软组织接枝后,已证明可以改
Under certain conditions, certain vinyl monomers can undergo graft copolymerization with many natural polymer compounds (such as rubber, cellulose, wool, casein, leather, etc.) to form graft copolymers. Such graft copolymers generally have the characteristics of both natural polymers and monomeric homopolymers. Therefore, graft copolymerization has been widely used for the modification of natural polymeric compounds. Collagen is an important component of biological tissue (such as skin, bone, connective tissue, etc.). Collagen and a variety of vinyl monomer graft copolymerization in recent years, many foreign reports. Different monomers on the collagen soft tissue grafting, has proved that can be changed
