Provided herein are polyolefin dispersants, as well as methods for producing polyolefin dispersants. The polyolefin dispersants can be defined by the formula below
where Rx is cationic initiator residue; Ra is a polyolefin group; R1 and R2 are each, independently in each —(CR1R2) unit, H, alkyl, alkoxy, or alkylaryl; R3 and R4 are each, independently, H, alkyl, or alkoxy; m is an integer from 1 to 20; n is an integer from 1 to 6; r is an integer from 1 to 4; Y is a polyvalent amine linker comprising one or more tertiary amines, wherein the polyvalent amine linker does not include a primary amine or a secondary amine; and A is absent, or comprises a dispersive moiety.
本文提供的是聚烯烃分散剂以及生产聚烯烃分散剂的方法。聚烯烃分散剂可按下式定义
其中 Rx 为阳离子引发剂残基;Ra 为聚烯烃基团;R1 和 R2 在每个-(CR1R2)单元中各自独立地为 H、烷基、烷氧基或烷基芳基;R3 和 R4 各自独立地为 H、烷基或烷氧基;m 为 1 至 20 的整数;n 是 1 到 6 的整数; r 是 1 到 4 的整数; Y 是多价胺连接体,包括一个或多个叔胺,其中多价胺连接体不包括伯胺或仲胺;以及 A 不存在,或包括一个分散基团。
