AMPHIPHILIC BLOCK POLYMERS PREPARED BY ALKENE METATHESIS

摘要

The invention relates to a multiblock polyolefin, and methods to make a multiblock polyolefin, represented by the formula (X) or (XII): PO-C(R11)R12-CR13C(R14-C)-C(O)-((CR15R16) ZVC17R18)m-O)n-R19 (X) or PO-C(R11)R12-CR13C(R14-C)-C(O)-((CR15R16) ZVC17R18)mO)n-C(O)- C(R14C=(R13)-C(R12)(R11)-PO (XX) wherein R11, R12, R13, and R14 are each independently a substituted or unsubstituted C1 through C4 hydrocarbyl group or a hydrogen; R15, R16, R17, and R18 are each independently a substituted or unsubstituted C1 through C4 hydrocarbyl group or a hydrogen; R19 is a C1 to a C20 substituted or unsubstituted hydrocarbyl group or a hydrogen; z is = 1 to about 5; m is = 1 to about 5; PO is a polyolefin hydrocarbyl group comprising 10 to 4000 carbon atoms; and n is from 1 to about 10,000.
