PREPARATION OF LOW RESIDUAL MONOMER CONTENT POLYMERS

摘要

Methods of preparing an acrylic polymer according to the present invention comprise the steps of: forming a gelled polymer by polymerizing a mixture containing an acrylic monomer and a photoinitiator; comminuting the gelled polymer to produce gel particles; and irradiating the gel particles with lig ht to decompose the photoinitiator, simultaneously with, or after, the step of comminuting. The gel particles may be irradiated with UV light while they ar e being dried in a fluid-bed dryer.
