PROCEDIMIENTO PARA PRODUCIR UN POLIMERO ACRILICO DE ALTO PE-SO MOLECULAR

摘要

The use of a cyclic compound containing a group, has been found to allow an acrylamide, acrylic acid and/or 2- acrylamide-2-methylpropane sulfonic acid and its salts to be polymerized to a polymer having improved performance characteristics and/or with improved rates of polymerization. Optionally, urea is added with the cyclic compound. The compound may be used by (i) adding it to the monomer before polymerisation and removing it before commencement of polymerisation; (ii) having it present during polymerisation or (iii) adding it to the polymer immediately after polymerisation and before drying.
