Abstract

The present invention relates to a process to make continuous strand polymer comprising the following steps: a) providing a monomer mixture comprising water, a monomer, a crosslinker and an initiator; b) transporting the monomer mixture of step a) into a confining means wherein the monomer mixture is confined in said confining means; c) initiating polymerization of the monomer mixture in the confining means to make a continuous strand polymer; and d) emitting the continuous strand polymer from the confining means wherein the continuous strand polymer has a defined cross-sectional profile comprising an initial cross sectional diameter of at least 0.1 mm. The present invention is further directed to a process of making a continuous strand superabsorbent polymer.
