Popis:	The polymer dispersed liquid crystal(PDLC) films were prepared by photopolymerization induced phase separation with macroinitiator(RAFT-PS) of different molecular weight,synthesized by RAFT polymerization.The influences of molecular weight of RAFT-PS on morphology,photopolymerization kinetics,nematic fraction and electro-optical pro-perties of PDLCs had been investigated.It was found that the key factor of affecting morphology was not the molecular weight of polymer matrix and the rate of polymerization but the molecular weight of RAFT-PS.On the other hand,the diameter of liquid crystal droplets was effectively controlled by changing the molecular weight of RAFT-PS.This result contributed to improve electro-optical properties of PDLCs.
