Acrylamidoacylated oligomers

Claim 1

A process for preparing an acrylamidoacyl or methacrylamidoacyl oligomer comprising the steps: (a) admixing (1) at least one alkenyl azlactone having the formula: ##STR9## wherein R 1 is hydrogen, chlorine, or a methyl group; R 2 is a single bond or a methylene or ethylene group that can be substituted by an alkyl group having 1 to 6 carbon atoms or a phenyl group; R 3 and R 4 are independently hydrogen, an alkyl or cycloalkyl group having 1 to 12 carbon atoms, a phenyl group or an alkyl-substituted phenyl group having 6 to 12 carbon atoms, or R 3 and R 4 taken together with the carbon atom to which they are attached form a 5- to 12-membered carbocyclic ring; and (2) per mole of alkenylazlactone about 0.8 to 1.2 equivalent weights of at least one nucleophilic group-substituted oligomer having a molecular weight in the range of 200 to 20,000 selected from a group consisting of (1) polyether polyols, (2) polyester polyols, (3) polyoxyalkylene polyamines (4) hydroxy- and amino-functional derivatives of polymerized fatty acids, (5) hydroxy- or amino-functional olefin polymers and copolymers, (6) primary or secondary amino-functional polyamides, (7) polyethyleneimines; (8) polyvinyl alcohol and other hydrolyzed or partially hydrolyzed vinyl acetate homo- and interpolymers, and (9) polysiloxane polyols; and (b) isolating said acrylamidoacyl or methacrylamidoacyl oligomer.
