Process for preparing functional polymers through addition of amino and polymeryl groups to aldehyde moieties

A process for producing a functional polymer comprising:

• reacting an aldehyde with a zinc composition in the presence of a Lewis acid having the formula (R2N)nMX4-n, wherein
• the zinc composition has the formula ZnR′2 or R1Zn[R′Zn—]YR1, and wherein:
• n is an integer from 1 to 3;
• X is Cl, Br, or I;
• R is a C1-10 hydrocarbon;
• M is a Group 4 metal;
• R′ in each occurrence is a polymer composition;
• R1 in each occurrence is independently selected from a polymer composition, alkyl, hydrogen, halide, amide, hydrocarbyl, hydrocarbylamide, dihydrocarbylamide, hydrocarbyloxide, hydrocarbylsulfide, dihydrocarbylphosphido, tri(hydrocarbyl)silyl;
• any hydrocarbyl group being optionally substituted with at least one halide, amide, hydrocarbylamide, dihydrocarbylamide, or hydrocarbyloxide;
• and each carbon-containing R1 having from 1 to 50 carbon atoms, inclusive;
• and
• Y, on average, in each occurrence is a number from 1-150, inclusive.
