Abstract

Developing efficient and powerful polymerization methodologies for the preparation of functional polymers is an important research topic in polymer science. Among the established polymerization methodologies, the synthesis of sulfur-containing polymers with carbon disulfide (CS2) as a starting material is less developed. In this work, a new synthetic route for sulfur-containing polymers was developed from CS2via the terpolymerization of active methylene compounds, CS2, and dihalohydrocarbons in the presence of K2CO3 at 0 °C to room temperature, affording poly(ketene dithioacetals) in excellent yields (yields up to 97.0%) with high molecular weights (Mw up to 33 900). All the polymers possess good solubility and high thermal stability. In addition, these sulfur-containing polymers exhibited a high refractive index of 1.62–1.75.
