A polymer comprising units having the structure (I):
wherein x is 2 or 3, wherein L is (CH2)y, where y is an integer from 1 to 10, or wherein L is CH(CH3)CH2S(CH2)z, where z is an integer from 1 to 5; wherein [Q] is absent or is a polymerised moiety consisting of units having the structure (II):
wherein R is a hydrocarbyl group, or a hydrocarbyl group containing one or more heteroatoms, wherein R may be linear, branched or cyclic, saturated or unsaturated, and wherein R has from 1 to 30 carbon atoms; wherein [Q] either consists of identical units of structure (II), or wherein [Q] consists of more than one different units of structure (II), differing in group R; and wherein X is a halogen or another chain terminating group. The polymers may find use as additives in lubricating compositions where they provide friction improvement and wear reduction.
一种聚合物,包含具有 (I) 结构的单元:
其中 x 为 2 或 3,其中 L 为 (CH2)y,其中 y 为 1 至 10 的整数,或其中 L 为 CH(CH3)CH2S(CH2)z,其中 z 为 1 至 5 的整数;其中 [Q] 不存在或为由具有结构 (II) 的单元组成的聚合分子:
其中 R 是烃基,或含有一个或多个杂原子的烃基,R 可以是线性、支链或环状、饱和或不饱和的,R 具有 1 至 30 个碳原子;其中 [Q] 或者由结构(II)相同的单元组成,或者 [Q] 由多个结构(II)不同的单元组成,以基团 R 不同;以及其中 X 是卤素或另一种链终止基团。这些聚合物可用作润滑组合物的添加剂,以改善摩擦和减少磨损。
