    Abstract: The present invention relates to a process for producing cling films, using biodegradable polyesters obtainable by polycondensation of: i) 65 to 80 mol%, based on the components i to ii, one or more dicarboxylic acid derivatives or dicarboxylic acids selected from the group consisting of: succinic acid, adipic acid, sebacic acid, azelaic acid and brassylic acid; ii) 35 to 20 mol%, based on the components i) to ii), of a terephthalic acid derivative; iii) 98 to 102 mol%, based on the components i) to ii), of a C2-C8 alkylenediol or C2-C6 oxyalkylenediol; iv) 0.1 to 2% by weight, based on the polymer obtainable from the components i to iii, of an at least trifunctional crosslinker or at least difunctional chain extender. In addition the invention relates to polymer mixtures which are particularly suitable for producing cling films, and to cling films which contain biodegradable polyesters.

    Abstract: The invention relates to a water-soluble or water-dispersible copolymer containing units, which can be embedded by polymerization, a) of at least one ethylenically unsaturated monomer comprising a saccharide side group and b) at least one hydrophilic monomer that is different from (meth)acrylamide and ethylenically unsaturated, wherein the percentage by weight of the ethylenically unsaturated monomers comprising a saccharide side group is 5 to 95 wt %. The copolymers exhibit high affinity to inorganic surfaces or hydrophilic fibers such as cotton. Said copolymers are used in textile detergents as polymers that are able to dissolve dirt and/or prevent graying or minimize the risk of the microbial colonization of materials coated therewith.

    Abstract: The invention relates to a method for producing tear-propagation-resistant foils using biologically degradable polyesters which can be obtained by polycondensation from: i) 65 to 80 mol %, based on components i to ii, of one or a plurality of dicarbonic acid derivatives or dicarbonic acids selected from the group consisting of: succinic acid, adipic acid, sebacic acid, azelaic acid and brassylic acid; ii) 35 to 20 mol %, based on components i to ii, of a terephthalic acid derivative; iii) 98 to 102 mol %, based on components i to ii, of a C2-C8 alkylene diol or C2-C6 oxyalkylene diol; iv) 0.05 to 2 wt %, based on the polymer obtainable from components i to iii, of an at least trifunctional crosslinker or of an at least difunctional chain extender. The invention further relates to polymer mixtures which are suitable for producing foils capable of tear propagation.
