Process for preparing an olefin-acrylate block copolymer

A process for preparing an olefin-acrylate block copolymer, the process comprising:

• a) combining starting materials comprising an organometallic compound, an acrylate monomer, and a metal salt component,
• thereby forming a product comprising the olefin-acrylate block copolymer, wherein:
• the metal salt component comprises a metal salt, a metal salt complex, or combinations thereof;
• the organometallic compound has the formula (I):
• the acrylate monomer has the formula (II):
• the olefin-acrylate block copolymer has the formula (III):
• n is greater than or equal to 0;
• each M independently is aluminum or zinc;
• if an M is zinc, then the subscript m of the attached J is equal to 0;
• if an M is aluminum, then the subscript m of the attached J is equal to 1;
• each R and J independently is a C1-C26 hydrocarbyl group or a polymeryl group,
• wherein each R and J may be the same or different;
• each R1 independently is a C1-C30 hydrocarbyl group;
• each R2 independently is hydrogen or a methyl group;
• R3 is J when n is equal to 0, and R3 is R when n is greater than 0;
• x is equal to 0 or a number from 2 to 500;
• x is equal to 0 when n is equal to 0;
• and
• y is a number from 2 to 500.
