ABSTRACT:
Preformed, homogeneous, non-linear starch copolymerizate articles may be prepared by copolymerizing a preformed, homogeneous mixture of water, ethylenically unsaturated starch and ethylenically unsaturated monomers to provide a labyrinth of copolymerized starch chains interconnected with each other by the copolymerized monomeric units. The invention is particularly suitable for preparing high-binder, aqueous coating compositions which may be applied to a variety of substrates and subsequently copolymerized with polymerization initiating systems. Improved water- and detergent-resistance may be obtained by incorporating film-forming additives, cross-linking reagents or polyunsaturated compounds into the copolymerizable starch composition.
