Amphiphilic block polymers prepared by alkene
Abstract:
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)—C(R13)═C(R14)—C(O)—O—((CR15R16)z—(CR17R18)m—O)n—R19  (X) or PO—C(R11)(R12)—C(R13)═C(R14)—C(O)—O—((CR15R16)z—(CR17R18)mO)n—C(O)—C(R14)═C(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.
