Polymers of 3-butene esters, their preparation and use
First Claim
1. An enamine functional polymer comprising the reaction product of an acetoacetoxy functionalized polymer and an amine selected from the group consisting of ammonia, a primary amine, and a secondary amine, wherein said acetoacetoxy polymer comprises the free-radical polymerization product of:
- a monomer of formula (I);
##STR7## where R1 and R2 are both a --C(O)R3 group;
R3, which can be the same or different, is selected from the group consisting of a C1 -C24 alkyl group, an aromatic or heteroaromatic group, a C3 -C8 cycloalkyl or C2 -C7 heterocyclic group, and a --CH2 --C(O)--R4 group;
R4 is a C1 -C6 alkyl group;
wherein at least one of R1 and R2 is an acetoacetoxy group;
and an ethylenically unsaturated monomer.

Abstract
The specification describes various polymers having monomer of formula (I): ##STR1## In formula (I), R1 and R2 are, independently, hydrogen, a C1 -C24 alkyl group, an aromatic or heteroaromatic group, a C3 -C8 cycloalkyl or C2 -C7 heterocycloalkyl group, or a --C(O)R3 group. Preferably R1 and R2 are both a a --C(O)R3 group where R3 which can the same of different is selected from the group consisting of a C1 -C24 alkyl group, an aromatic or heteroaromatic group, a C3 -C8 cycloalkyl or C2 -C7 heterocyclic group; or a --CH2 --C(O)--R4 group in which R4 is a C1 -C6 alkyl group. At lease one of R1 and R2 is a --C(O)R3 group. The polymer may be a homopolymer or a copolymer containing other ethylenically unsaturated monomers. The polymer may be used in a variety of coating compositions such as inks, adhesives, paints and films. Unique monomers where both R1 and R2 are acetoacetyl groups and novel monomers where R2 is an acetoacetyl group are also described.
