具有低粘度和高粘度指数的封端的油溶性聚亚烷基二醇
摘要：
一种封端的油溶性聚亚烷基二醇，其具有以下结构：R1O‑(AO)n‑R2，其中：R1为具有1到18个碳原子的直链或支链烷基或芳基；AO是指选自所选择的1,2‑环氧丁烷和1,2‑环氧丙烷的单体的残基，使得至少50重量％的所述(AO)n组分为1,2‑环氧丁烷残基；选择n来为未封端的聚亚烷基二醇提供在100℃下小于5厘沲的运动粘度；并且R2为具有1到8个碳原子的直链或分支链烷基或芳基，并且其中所述封端的油溶性聚亚烷基二醇的特征在于具有在100℃下小于4.5厘沲的运动粘度和大于150的粘度指数。
摘要（英）：

A capped oil soluble polyalkylene glycol has the following structure: R1O-(AO)n-R2 where: R1 is a linear or branched alkyl or aryl with one to 18 carbon atoms; AO refers to residuals of monomers selected from 1,2-butylene oxide and 1,2-propylene oxide selected so that at least 50 weight-percent of the (AO)n component is 1,2-butylene oxide residuals; n is selected to provide a kinematic viscosity at 100 degrees Celsius of less than 5 centiStokes for the non-capped polyalkylene glycol; and R2 is a linear or branched alkyl or aryl having from 1-8 carbon atoms and wherein the capped oil soluble polyalkylene glycol is characterized by having a kinematic viscosity of less than 4.5 centiStokes at 100 degrees Celsius and a viscosity index of greater than 150.
