An aqueous emulsion interpolymer composition capable of forming stable films which have excellent protective properties, especially on metallic substrates, good chemical resistance and/or permeability to water vapor, comprising particles suspended in an aqueous solution made by interpolymerizing an acrylic latex seed particle with a vinylidene chloride polymer comprising vinylidene chloride, one or more alkyl acrylates having from 1 to 18 carbon atoms in the alkyl group and/or one or more alkyl methacrylates having 1 to 18 carbon atoms in the alkyl group, one or more aliphatic alpha-beta-unsaturated carboxylic acids, and a copolymerizable surface active agent, the proportion of vinylidene chloride being 65 to 90 parts by weight, the portion of said alkyl acrylates and/or methacrylates being from 2 to 30 parts by weights, the portion of said carboxylic acids being from 0.1 to 20 parts by weight, and the portion of said copolymerizable surface active agent being from 0.1 to 5.0 parts by weight.

Reactive multifunctional imide monomers have been discovered from which radiation curable oligomers and polymers may be derived. The reactive imide monomers have at least one functional group which is polymerizable under free radical or ionic polymerization conditions with other similar functional groups. However, the same functional group and reaction product derived therefrom is substantially not subject to cleavage by oxidation or hydrolysis. The reactive imide monomer also contains at least one other functional group which remains intact under the above-described polymerization conditions to form a part of a side chain of the resultant polymer and will cross-link or cure by 2+2 cyclo-addition with other like functional groups upon irradiation.

The present invention is directed to a reactive diluent comprising a backbone portion and a pendant group portion. The backbone portion comprises at least two polymerizable sites, and the pendant group portion comprising a functional group having the following formula: ##STR1## wherein Z is an ethylenically unsaturated hydrocarbyl or substituted hydrocarbyl group containing from 2 to about 12 carbon atoms and wherein said pendant group is capable of a (2+2) cyclo-addition with another like pendant group of the above formula. The chain extending reaction site is preferably used in a polymerization reaction to provide a polymeric material, and the cross-linking reactive site is preferably used to create cross-linking as needed or desired.
