ABSTRACT Polymeric Products and their Production A particulate substantially homogeneous polymeric product is made by dispersing ungelatinised polysaccharide in aqueous monomer containing polymerisation initiator, initiating polymerisation and thereby inducing exothermic polymerisation, utilising the exotherm to provide part at least of the heat necessary to gelatinise the polysaccharide and thereby producing a comminutable gel comprising polymerised monomer and gelatinised polysaccharide, comminuting the gel and drying the comminuted gel. The product generally comprises a blend of water soluble synthetic polymer, gelatinised polysaccharide having a low degree of graft polymerisation and optionally gelatinised polysaccharide. Products comprising these components are particularly suitable for use as wallpaper adhesives.
