Claims
- 1. A polymeric material obtained by homopolymerization, copolymerization or grafting as a side chain onto a constituent unit of a homopolymer or copolymer, or grafted onto a monomer which is then polymerized or copolymerized, of a compound of formula I: ##STR8## wherein the entity ##STR9## represents a nitrogenous aromatic heterocyclyl radical comprising 1 to 4 nitrogen atoms chosen from pyridinyl, pyrazinyl, pyrimidinyl or triazinyl and containing at least one nitrogen atom in the .alpha. position with respect to the CH.dbd.CH double bond,
- X.sub.1 and X.sub.2 are, independently of one another, conjugated aliphatic systems themselves conjugated with the remainder of the molecule, or aromatic cyclic or aromatic heterocyclic systems, which are unsubstituted or substituted one or more times with radicals chosen from the following group: alkyl, halo, phenyl, naphthyl, hydroxyl, alkoxy, amino, lower alkylamino, lower dialkylamino, lower alkyl(lower alkoxy)amino, (lower alkylacyl)aminocarbonyl, lower alkylcarbonyl, lower alkoxycarbonyl, carboxyl, (lower alkylamino)carbonyl, (lower dialkylamino)carbonyl, halocarbonyl, trifluoromethyl, nitro, nitroso, cyano, 2,2-dicyanovinyl, 3,3-dicyanoprop-2-enyl, tricyanovinyl, dicyanomethylidenyl, mercapto, alkylthio, sulfino, alkylsulfonyl, sulfo, alkylsulfonyloxy, alkylsulfinyl, pyridinyl and conjugated pyridinyl derivatives.
- 2. The polymeric material of claim 1 wherein the compound of formula I has a functionality greater than or equal to 1 and the compound of formula I is grafted as the side chain.
- 3. The polymeric material of claim 2 wherein the compound of formula I is grafted as the side chain onto a polyolefin, polyester, polyamide, poly(vinyl acetate), poly(vinyl chloride), polyurethane, poly(methyl methacrylate) or hydroxyethylcellulose.
- 4. The polymeric material of claim 1 wherein the compound of formula I has a functionality greater than or equal to 2 and the polymeric material is obtained by homopolymerization or copolymerization.
