Poly (alkyl epdxides), process for making, and lubricant compositions having same

专利摘要

A process for making a poly(alkyl epoxide). The process has the step of polymerizing one or more alkyl epoxide monomers in the presence of a cationic catalyst according to the following sequences:wherein R1, R2, R3, and R4 are hydrogen or alkyl moieties that, taken together, have a total of 1 to 80 carbons; wherein any of R1, R2, R3, and R4 can be linear or branched if it is an alkyl moiety; wherein “m” is an integer from 1 to 4; and wherein “n” is an integer from 2 to 120. There is also another process for making a poly(alkyl epoxide) using an initiator. There are also poly(alkyl epoxides). There is also a lubricant composition having a first lubricant base stock of one or more poly(alkyl epoxides) and a second lubricant base stock different than the first lubricant base stock. ......

权利要求: 1. A process for making a poly(alkyl epoxide), comprising: polymerizing one or more alkyl epoxide monomers in the presence of a Lewis acid catalyst according to the following sequence:wherein at least one of R1 or R2 and at least one of R3 or R4 are an alkyl moiety and wherein R1, R2, R3, and R4 are hydrogen or alkyl moieties that, taken together, have a total of 1 to 80 carbons; wherein any of R1, R2, R3, and R4 can be linear or branched if it is an alkyl moiety; wherein “m” is 1; and wherein “n” is an integer from 2 to 120, wherein the poly(alkylepoxide) has a Viscosity Index ranging from 70 to 81.2. The process of claim 1, wherein the Lewis acid is selected from the group consisting of selected from the group consisting of AlCl3, BF3, AlBr3, TiCl3, and TiCl4 either alone or with a protic promoter.3. The process of claim 1, wherein the Lewis acid is selected from the group consisting of a synthetic or natural zeolites, an acid clay, a polymeric acidic resin, an amorphous solid catalyst, a heteropoly acid, a tungsten zirconate, a tungsten molybdate, a tungsten vanadate, a phosphotungstate, and a molybdotungstovanadogermanate.4. The process of claim 1, wherein the one or more alkyl epoxides is selected from the group consisting of ethylene oxide, 1,2-epoxybutane, 1,2-epoxyoctane, and 1,2-epoxydecane.5. The process of claim 1, wherein the polymerizing is carried out at a temperature of −30° C. to 125° C.6. The process of claim 1, wherein the polymerizing is carried for a time of 1 hour to 24 hours.7. A process for making a poly(alkyl epoxide) comprising polymerizing one or more alkyl epoxide monomers in the presence of a Lewis acid catalyst and an initiator of R′OH according to the following sequence:wherein at least one of R1 or R2 and at least one of R3 or R4 are an alkyl moiety and wherein R1, R2, R3, and R4 are hydrogen or alkyl moieties that, taken together, have a total of 1 to 80 carbons; wherein any of R1, R2, R3, and R4 can be linear or branched if it is an alkyl moiety; wherein “m” is 1; and wherein “n” is an integer from 2 to 120, wherein the poly(alkylepoxide) has a Viscosity Index ranging from 70 to 81.8. The process of claim 7, wherein the Lewis acid is selected from the group consisting of selected from the group consisting of AlCl3, BF3, AlBr3, TiCl3, and TiCl4 either alone or with a protic promoter.9. The process of claim 7, wherein the Lewis acid is selected from the group consisting of a synthetic or natural zeolites, an acid clay, a polymeric acidic resin, an amorphous solid catalyst, a heteropoly acid, a tungsten zirconate, a tungsten molybdate, a tungsten vanadate, a phosphotungstate, and a molybdotungstovanadogermanate.10. The process of claim 7, wherein the one or more alkyl epoxides is selected from the group consisting of ethylene oxide 1,2-epoxybutane, 1,2-epoxyoctane, and 1,2-epoxydecane.11. The process of claim 7, wherein the polymerizing is carried out at a temperature of ˜30° C. to 125° C.12. The process of claim 7, wherein the polymerizing is carried for a time of 1 hour to 24 hours.
