近十年来,在大分子化学领域中,尽管已进行了大量工作;但有目的地合成一些高聚物以作药物应用,在当前仍然是未开拓的领域。一般说来,在生物体内,大分子与非大分子物质相比,可预期具有不同的实质性效果。某些大分子物质可能作为药物应用于临床,是基于:(1)高分子聚合物注射到生物体 In the past decade, in the field of macromolecular chemistry, although a great deal of work has been done, it is still an unexplored area to synthesize some polymers for drug use purposefully. In general, macromolecules are expected to have different substantive effects in vivo than non-macromolecular substances. Some macromolecular substances may be used as clinical medicine, is based on: (1) polymer injected into the organism
