Examples of groups Y have benzene, naphthalene, furane, thiophene and pyridine nuclei and alkyl, alkoxy, alkylamino, carbalkoxy, hydroxy, nitro, chloro and bromo substituents. The esters are prepared by reacting vinyl or polyvinyl phosphonic acid dichloride with a hydroxyalkyl ether of the appropriate chalcone in an inert anhydrous solvent in the presence of an acid binding agent, such as a tertiary organic base, and treating the product with water to saponify the second chlorine atom. The 4-(beta hydroxy-ethoxy) chalcones are prepared by reacting molar quantities of beta-hydroxyethoxy-acetophenone with the appropriate aromatic or heterocyclic aldehyde in the presence of an alkaline condensation agent or, in some cases, hydrogen chloride. The omega -4-(hydroxy - ethoxy) - chalcones are prepared from 4-(beta - hydroxy - ethoxy) benzaldehyde and a nuclear-substituted acetophenone. Detailed preparations are given for compounds having formulae 1 to 12 shown in the drawings and for the hydroxyethoxy chalcones used to prepare them.ALSO:Light-sensitive materials for printing plates (see Division G2) contain compounds which photopolymerize without sensitisers or catalysts and which are esters of vinyl or polyvinyl phosphonic acid having one OH on each P esterified with an alcohol: HO-CH2-CH2-O-C6H4-CO-CH=CH-Y; HO-CH2-CH2-O-C6H4-CO-CH= CH-CH=CH-Y or HO-CH2-CH2-O-C6H4-CH=CH-CO-Y; where Y is a substituted or unsubstituted mono- or multi-nuclear aromatic or heterocyclic groups. Examples of groups Y have benzene, naphthalene, furane, thiophene and pyridine nuclei and alkyl, alkoxy, alkylamino, hydroxy, nitro, chloro, and bromo substituents. The preparation of such esters is described (see Division C2) including the step of polymerizing vinyl phosphonic acid dichloride in solution in benzene, dioxane or ethyl acetate using benzoyl peroxide or azodiisobutyronitrile as catalyst. Compounds used in specific examples are those having formulae 1 to 12 shown in the drawings. <FORM:0947471/C3/1> <FORM:0947471/C3/2> <FORM:0947471/C3/3> <FORM:0947471/C3/4> <FORM:0947471/C3/5> <FORM:0947471/C3/6> <FORM:0947471/C3/7> <FORM:0947471/C3/8> <FORM:0947471/C3/9> <FORM:0947471/C3/100> <FORM:0947471/C3/111 <FORM:0947471/C3/122> |
