    摘要: Thermoplastically moldable, biodegradable, starch-containing polymer blends consisting essentially ofA) 100 parts by weight of anhydrous starch,B) from 0.1 to 70 parts by weight of polyurethane containing urea groups and based on selected starting materials,C) from 0.5 to 70 parts by weight of a plasticizer component andD) from 2 to 20 parts by weight of water,a process for producing these blends by mixing the individual components in plastics processing machines and their use for producing moldings, films, fibers, coatings or laminates by thermoplastic processing.

    摘要: Novel laminates comprise transparent polymers with a high content of hydroxyl groups as core layer and adhesive layers applied to one or both sides which are tack-free under normal conditions and which can accept an outer layer, thermoplastic polyurethane-polyureas having a substantially linear molecular structure with exclusively aliphatically or cycloaliphatically bonded urethane segments and urea segments and a content of urea groups --NH--CO--NH-- of 1 to 20% by weight and a content of carboxyl groups --COOH bonded directly to the main chain of the molecule in lateral positions, of 0.001 to 10% by weight, being used as adhesive layers.
