Abstract:
A copolymer composition comprising a copolymer comprised of at least 30 mol % of residues having the following alternating structural units:â€”[DMâ€”AM]â€”wherein DM represents a residue from a donor monomer, AM represents a residue from an acceptor monomer, at least 15 mol % of the copolymer comprising a donor monomer having the following structure (I): wherein R1 is linear or branched C1 to C4 alkyl, R2 is selected from the group consisting of methyl, linear, cyclic or branched C1 to C20 alkyl, alkenyl, aryl, alkaryl and aralkyl, at least 15 mol % of the copolymer comprising an acrylic monomer as an acceptor monomer, wherein the copolymer is substantially free of maleate monomer segments and fumarate monomer segments and the copolymer composition is substantially free of Lewis acids and transition metals.
