| Abstract: | Poly(methyl methacrylate)(PMMA, PDI 1. 44) was prepared by RAFT-miniemulsion poly-merization, using MMA as monomer and S-1-dodecyl-S′-(α,α-dimethyl-α″-acetic acid) trithiocarbon-ate as chain transfer agent. Poly( methyl methacrylate)-b-poly( glycidyl methacrylate) diblock copoly-mer(1) was synthesized using PMMA miniemulsion as seed emulsion and glycidyl methacrylate as the second monomer. The structures and properties were confirmed by 1 H NMR, FT-IR, GPC and DSC. The results showed that the PDI and Tg of 1 were 2. 04 and 92. 35 ℃, respectively. |
