表面活性单体存在下的MMA/BA──乳液共聚合(Ⅲ)乳液的稳定性

Emulsion Copolymerization of MMA/BA in the Presence of Surface Active Monomers(Ⅲ)——Latex Stability

研究了 ZC-L,ZD-L 等表面活性单体存在下 ,MMA,BA和 MMA/ BA乳液聚合的稳定性 .制得了不含游离乳化剂 ,固含量在 40 %以上的 PMMA,PBA以及 P(MMA/ BA)稳定乳液 .

The latex stabilities of MMA, BA and MMA/BA emulsion polymerization in the presence of two homemade surface-active monomers(Surfmers) [sodium sulfonated lauryl(allyl glyceryl) succinate(ZC-L) and sodium sulfonated lauryl(methacryloyl glyceryl) succinate(ZD-L)] were investigated. Excellently stable PMMA, PBA and P(MMA/BA) latexes with no free emulsifiers and solid content over 40% were prepared.
