2-Oxocyclohexyl acrylate, phenacyl acrylate, α-trichloromethyl-β-carbomethoxyethyl acrylate and β, β, β-trichloroisopropyl acrylate have been prepared readily by the condensation of acryloyl chloride and the corresponding alcohol with the aid of triethylamine (equation A).
CH2=CHCOCl + ROH N (C2H5)3→ CH2=CHCOOR (A)
By the alcoholysis of methyl acrylate and methyl methacrylate with 2, 4, 4, 4-tetrachlorobutanol-1, 2, 4, 4, 4-tetrachlorobutyl acrylate and 2, 4, 4, 4-tetrachlorobutyl methacrylatehave also been prepared (equation B).
CH2=CR'COOCH3 + ROH H2SO4→ CH2=CR'COOR (B)
These new acrylates and methacrylate have been polymerized in dioxane using 2, 2'-azobisisobutyronitrile as an initiator.
Among others, the Polyacrylates and the polymethacrylates having three to four chlorine atoms in one unit of the polymer chain give films which do not burn.
