  Blends are formed with numerous commercially available resins and a comb-shaped polymer ("comb" for brevity) of a macromolecular monomer of a polylactone having terminal vinyl unsaturation so long as the polylactone chains are long enough to be compatible with one of the components to be blended. The comb may be formed with any polymerizable olefinically unsaturated monomer, preferably a vinyl, styryl, or acryloyl monomer. The vinyl unsaturation of the "head" of the macromer of polylactone may be acryloyl, styryl or allyl. The comb is made by a low temperature emulsion or suspension polymerization process. The comb, which has a hydrocarbon backbone and pendant polylactone chains, typically has a number average molecular weight of at least 10,000. A blend of first and second resins which are normally incompatible with each other, is also produced using a comb in which the backbone is compatible with one of the resins. Such blends also result with a synthetic resin and a comb in which the pendant chains consist of a first block which has a polylactone structure, and a second block which has a polyether structure, or vice versa.

  混合物是由多种市售树脂和一种梳状聚合物（简称 "梳子"）形成的，梳子是由具有乙烯基不饱和末端的聚内酯大分子单体组成，只要聚内酯链足够长，能与其中一种要混合的成分相容即可。梳子可以用任何可聚合的烯烃不饱和单体形成，最好是乙烯基、苯乙烯基或丙烯酰基单体。聚乳酸大单体 "头部 "的乙烯基不饱和度可以是丙烯酰基、苯乙烯基或烯丙基。梳子是通过低温乳液或悬浮聚合工艺制成的。梳子具有烃骨架和下垂的聚乳酸链，其平均分子量通常至少为 10,000。使用骨架与其中一种树脂相容的梳子，还可以生产出通常互不相容的第一种和第二种树脂的混合物。使用合成树脂和梳子也可以产生这种混合物，其中的垂链由具有聚乳酮结构的第一嵌段和具有聚醚结构的第二嵌段组成，反之亦然。
