Abstract
A new route for the synthesis of polycarbonates in reactions of cyclic carbonates with potassium naphthalene and α,ω-dihalo compounds is presented. The mechanism of carbonate linkage formation involving 1,3-dioxolan-2-one ring opening is discussed. When oxiranes and CO2 were used instead of cyclic carbonates a product containing inbuilt polyether segments of various lengths was formed. It was found that the reaction of “living” polystyrene with cyclic carbonates and dihalo compounds given products containing polystyrene blocks in the polymer chains. The effects of various agents activating carbonate anions on yield and molecular weight of polycarbonates are examined.
