Unsaturated ester-amides of halogenated alkenes

Claim 1

A polymerization product of an ester-amide of an α,β-ethylenic unsaturated polycarboxylic acid selected from the class consisting of maleic, fumaric, methyl and dimethyl maleic and fumaric, mono and dichloromaleic and fumaric, dibromo maleic and fumaric, itaconic and aconitic acids, one of the acid groups therein being esterified by a halogenated alcohol having the formula ##STR88## wherein R is a divalent hydrocarbon radical having 1-10 carbon atoms therein, R' is selected from the class of H and monovalent hydrocarbon radicals of 1-20 carbon atoms, and X is bromine or chlorine, the second acid group being converted to an amide group of the formula --CONR" 2 wherein R" is a group selected from the class consisting of hydrogen and hydrocarbon groups of 1-20 carbon atoms and derivatives of said hydrocarbon groups in which derivative there is only one derivative group selected from the class consisting of --OH or --NH 2 , and when the polycarboxylic acid is aconitic acid, the third acid group is similarly amidified or unesterified or esterified with an alcohol selected from the class consisting of methyl, ethyl, propyl, amyl, hexyl, stearyl, benzyl, vinyl, allyl, methallyl, propargyl, butynyl, or crotyl, beta-N,N-dimethylaminoethyl, cyclohexyl, beta-hydroxyethyl, beta-bydroxypropyl, and ##STR89## alcohol.
