Abstract

A free-radical polymerization process for making macromonomers having the structure: comprising contacting: (a) CH2═CHY; (b) optionally, CH2═CXB; and (c) free-radicals, produced from a free-radical source; in which B, U, X, Y, Z, m, n and p are defined in the text; macromonomer quality being controlled by adjusting one or more of the following variables: molar ratios of a, b and c; temperature; monomer concentration; and conversion.
