Process for the production of a polymerized material and the product produced thereby |
摘要 |
A polymerized material produced by the polymerization of an organic amide monomer in the presence of an organic carbonate and a process for the preparation thereof. The process comprises the steps of: heating an amount of the organic anide monomer to a temperature above its melting point; first mixing an amount of an anionic initiator with at least a portion of the amount of heated organic amide mnonomer to produce an amount of activated monomer, wherein the anionic initiator is not comprised of an alkali metal; second mixing an amount of the organic carbonate with at least a portion of the amount of heated organic amide monomer to produce an amount of dissolved organic carbonate; and polymerizing the amounts of heated organic amide monomer and activated monomer in the presence of the amount of dissolved organic carbonate to produce the polymerized material.
