摘要：Preformed, homogeneous, non-linear starch copolymerizate articles may beprepared by copolymerizing a preformed, homogeneous mixture of water, ethylenicallyunsaturated starch and ethylenically unsaturated monomers to provide a labyrinth ofcopolymerized starch chains interconnected with each other by the copolymerizedmonomeric units. The invention is particularly suitable for preparing high-binder, aqueouscoating compositions which may be applied to a variety of substrates and subsequentlycopolymerized with polymerization initiating systems. Improved water- and detergent-resistance may be obtained by incorporating film-forming additives, cross-linkingreagents or polyunsaturated compounds into the copolymerizable starch composition.
