  • 本文是探討以RAFT聚合法,採用自發性相反轉、無界面活性劑乳化聚合法合成具有不同奈米級顆粒大小特用型核殼型橡膠(s-CSR) 添加劑,及以傳統乳化聚合法合成不同奈米級顆粒大小通用型核殼型橡膠(gp-CSR),作為不飽和聚酯樹脂(UP),環氧樹脂(EPR)及乙烯基酯樹脂(VER)的抗體積收縮劑(LPA)及增韌劑。吾人並合成不同化學結構之傳統UP,包括MA-PG型、MA-PA-PG型UP,及vinyl ester resin (VER),進而設計出具不同相溶性之苯乙烯(St)/UP(或VER)/s-CSR(或gp-CSR)三成份系統。S-CSR以聚丙烯酸乙酯PBA為軟質核心,以丙烯酸及丙烯酸甲酯poly(methyl acrylate-co-acrylic acid)為外殼,Gp-CSR則以聚丙烯酸乙酯PBA為軟質核心,以丙烯酸甲酯PMA為外殼,另外,S-CSR與gp-CSR之外殼吾人亦以甲基丙烯酸環丙氧酯(Glycidyl methacrylate, GMA)改質,以合成出具高極性及具特殊官能基基團外殼,如環氧基團或不飽和c=c雙鍵之s-CSR,以增加CSR外殼之極性及與樹脂基材化學交聯之能力。


    Synthesis of s-CSR by RAFT polymerization viaspontaneous phase inversion process and RAFT surfactant-free, batch emulsion polymerizationas low-profile additives (LPA) and tougheners for unsaturated polyester resins (UP) ,epoxy resin (EPR) and vinyl ester resin (VER) have been investigated . Two types of conventional unsaturated polyester resin with different chemical structures, namely, MA-PG type of UP and, MA-PA-PG type of UP, and vinyl ester resin (VER) ,have also been synthesized so that styrene (St) /UP(or VER) /CSR or EPR/DDM/CSR ternary systems with different miscibility can be designed.

    In the synthesis of the core-shell rubber,the core was made from butyl acrylate(BA),whereas the shell was made from acrylic acid(AA),and methyl acrylate(MA). Also, the shell of the s-CSR was modified by glycidyl methacrylate(GMA) or methacrylic acid(MAA) as a comonomer to both increase the molecular polarity and provide the specific functionality,such as epoxy group and unsaturated C=C bonds, for the shell of the CSR.
