Vinylester was syntheszed in the presence of amine and metal catalysts, such as triethylamine(TEA), triethylbenzyl ammonium chloride (TEBAC), cetyltrimethyl ammonium bromide (CTMAB), chromium acety] acetate (CAA), and triphenylantimony (TPA). Apropriate use of amine and organometal catalysts were 1.7~2.2 % (Wt. %), 2.5~3.1 % (Wt %) of charged methacrylic acid (MAA) in respect of reactivity, gel-time, and storage stability. The Order of reactivity was TEA>TEBAC>CTMAB>CAA>TPA. Temperature independence of catalyst showed more large deviation above $110^{\circ}C$. Storage stability could be improved without delay of gel-time by adding TPA in 2.0 % (Wt %) of charged MAA after synthesis.
