Abstract A series of water-soluble semirigid thermoresponsive polymers with well-defined molecular weights based on mesogen-jacketed liquid crystal polymers (MJLCPs), poly [bis (N-hydroxyisopropyl pyrrolidone) 2-vinylterephthalate](PHIPPVTA) have been synthesized via reversible addition fragmentation chain transfer (RAFT) polymerization. Dynamic light scattering (DLS) revealed that the novel monomer and polymers have thermoresponsive ...
