ABSTRACT:
This invention relates to a multi-step process for preparing a storage-stable dispersion of a biocide which comprises the steps of: (a) contacting a heat-swellable resin with a carrier to provide a liquid mixture of a resin and a carrier, (b) heating said liquid mixture to an elevated temperature to cause the resin to swell by virtue of carrier absorption into the resin to provide a swelled resin in said liquid mixture, and (c) adding a biocide to said swelled resin and mixing to provide a homogeneous, storage-stable liquid dispersion.
