摘要：

In order to synthesize liquid crystalline polymers with controlled structure, the stable free radical polymerization (SFRP) technique was employed to obtain homopolymers and block copolymers based on mesogenic acrylates. By the use of the stable free radical 2,2,6,6-tetramethyl-piperidinyl-1-oxy (TEMPO) we have obtained resins with polydispersity index (PDI) below the limiting theoretical value of 1.5, established for conventional free radical polymerization of acrylates.
