Abstract
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
합성촉매로 triethylamine(TEA), triethylbenzyl ammonium chloride(TEBAC), cetyltrimethyl ammonium bromide(CTMAB) 등의 아민 및 chromium acetyl acetate(CAA), triphenylantimony(TPA) 등의 유기금속화합물을 사용하여 합성촉매가 비닐에스테르수지의 합성 및 물성에 미치는 영향을 연구하였다. 반응성, 경화시간, 저장안정성 등을 고려해 볼 때, 촉매의 적절한 사용량은 methacrylic acid(MAA)에 대하여 아민계의 경우에는 1.7~2.2%(중량 %), 유기금속계의 경우에는 2.5~3.1%(중량 %)였다. 촉매의 반응성은 TEA>TEBAC>CT-MAB>CAA>TPA의 순이었으며, 촉매의 온도의존성은
