Abstract
An intimate water soluble or water swellable blend of microbial polysaccharide and synthetic polymer derived from water soluble monomer or monomer blend is made by forming an emulsion in non-aqueous liquid of an aqueous fermentation solution of the microbial polysaccharide and the monomer or monomer blend and then polymerizing the monomer or monomer blend to form a dispersion in non-aqueous liquid of aqueous particles of the water soluble or water swellable blend. This dispersion may then be dehydrated.
