Metallocene complexes initiated by initiators and cocatalysts produce the active

species for living free radical and coordination polymerization, respectively. It will

come true the unit of free radical and coordination polymerization in one polymer

molecule to prepare the co-polymer of aPS-b-polyolefins with functional group -OH on the chain end. It is a new concept in the field of polymer science. The effect of the

catalyst structure, the ratio of catalyst to cocatalyst, cocatalysts and polymerization

conditions on the synthesis, structure and properties of the co-polymer are

investigated. The polymerization mechanism, the relationship of the structure and

properties of the metallocene complexes, and of the structure and properties of the copolymer will be studied systematically, which will improve the novel polymerization

method and develop the novel polymer materials.
