NEW MATERIAL:A diacrylate dicarboxylic acid expressed by formula I [R<1>, R<2>, R<3> and R<4> are H or -CH2-CH2-OCO-CR=CH2 (R is H or CH3); R<1> and R<2> and R<3> and R<4> are not mutually equal)]. EXAMPLE:A compound expressed by formula II. USE:Useful as a monomer for ultraviolet (UV) curing type ink and coating, having extremely high chemical activity and capable of forming tough films similarly to other acrylic compounds by applying alone or together with other fillers, high polymer materials, such as vinyl based polymers, polyesters or polyamides, onto a metal, glass or high polymer material and optically or thermally crosslinking with acrylic double bonds in the compound. PREPARATION:A compound expressed by formula III is reacted with beta- hydroxyethyl acrylate in the presence of a catalyst and polymerization inhibitor to afford the aimed compound expressed by formula I. |
