摘要：An environmentally friendly stable aqueous optionally structured water-resistant architectural coating composition (especially a paint) containing a film-formingbinder polymer composed of a starch modified by the presence of carboxylic acid orinorganic carboxylate groups and bonded (probably grafted) to chains of copolymerizedmono-ethylenically unsaturated monomers (e.g. “acrylic”, “vinyl” or “styrenic”copolymers) permitting a stable aqueous dispersion of the binder polymer to be madewhich retains good water-resistance in the dried paint. The modified starch allows paintsto be made with less dependence on materials obtained from non-renewable resourceswhile retaining a low water-sensitivity.
