Preparation of Syndiotactic Poly(vinyl alcohol) Particles Using Emulsion Copolymerization of Vinyl Pivalate and Vinyl Acetate and Heterogeneous Surface Saponification. |
| 초록 |
Poly(vinyl pivalate/vinyl acetate) micro- and nano-particles prepared by emulsion copolymerization of vinyl pivalate (VPi) and vinyl acetate (VAc) with various monomer ratios at low temperature using 2,2-azobis(2-amidinopropane) dihydrochloride (AAPH) as an initiator and sodium dodecyl sulfate (SDS) as an emulsifier. The effect of the polymerization conditions on the conversion, molecular weight, and particle size distribution was investigated. From the emulsion copolymerization of VPi and VAc, spherical P(VPi/VAc) with high yield was effectively prepared, which might be useful for the precursor of syndiotactic poly(vinyl alcohol) (PVA) micro- and nano-particles with various surface properties. And then, various PVA/P(VPi/VAc) skin/core-structured micro- and nano-particles were obtained through the heterogeneous surface saponification of P(VPi/VAc) particles. |
