| description | The precipitation polymerization of styrene‐trihydroxymethyl propane triacrylate has been carried out using ethanol and an ethanol/water mixture as the solvent. Uniform microspheres with high monomer conversion are achieved within 4 h, a much shorter polymerization time than that reported for the precipitation polymerization of divinyl benzene‐styrene in acetonitrile. The results clearly demonstrate that use of water as a co‐solvent is indeed very effective to promote the polymerization to high conversion and to obtain uniform microspheres. With no water under the otherwise same experimental conditions, only about 57% of monomer conversion is obtained; while the monomer conversion is remarkably increased to 96% when 12 vol.‐% of water is used.
Uniform microspheres of St‐TMPTA are successfully prepared using ethanol and an ethanol/water mixture instead of acetonitrile. A high monomer conversion of up to 95% is obtained within a much shorter polymerization time (4 h) than those reported. Results reveal that the use of water as a co‐solvent is indeed very effective to promote the polymerization to high conversions and to obtain uniform microspheres. |
