DILITHIUM INITIATOR AND SYNTHESIS OF SBS BY ONE STEP FEED METHOD
一种双锂引发剂及一步法合成SBS

Dilithium initiator (LM-T) based on lithium-Aromatic complex was studied. Using LM-T as initiator and non-palar hydrocarbon as polymerization solvent, styrene-buta-diene-styrene triblock copolymer (SBS) was syntherized by one-step feed method. The characterization of SBS obtained by this initiator was curried out by means of IE, NME, GPC and mechanical properties determination. Comparison was made with sample prepared with monolithium initiator by twostep feed methed.
