Preparation of PVAc Particles by Dispersion Polymerization

摘要：

　　Highly uniform polyvinylacetate particles of submicron size were prepared by dispersion polymerization in mixed media of isopropanol and water initiated by redox initiator of NaHSO3 and K2S2O8 using poly(N-vinylpyrrolidone) as stabilizer.Monomer conversion was studied gravimetrically.Both the morphology and the size of the particles were measured by TEM.The influences of various polymerization parameters,such as monomer concentration,stabilizer content,on the particle properties were systematically investigated.The PVAc particles synthesized in this research were mono-disperse spheres with the diameter between 100-1000nm.
