Abstract: The invention relates to a protective adhesive film made of a polymer film which is coated with a crosslinked adhesive composition. The adhesive composition contains an adhesive polymer which is made by means of an emulsion polymerization in the presence of starches made of soft monomers, which when polymerized as homopolymers have a glass-transition temperature of less than 0 °C, ethylenically unsaturated acids or acid anhydrides, and optionally additional monomers that differ from (i) and (ii). The adhesive composition contains specific crosslinking agents, wherein the crosslinking reaction caused by the crosslinking agents ends before the protective adhesive film is adhered onto a substrate.

Abstract: The invention relates to a finely divided, starch-containing aqueous polymer dispersion which is obtainable by free radical emulsion polymerization of ethylenically unsaturated monomers in the presence of at least one redox initiator and starch, wherein the ethylenically unsaturated monomers comprise (a) from 30 to 65% by weight of acrylonitrile and/or methacrylonitrile, (b) from 35 to 60% by weight of at least one C1-C12-alkyl acrylate and/or at least one C1-C12-alkyl methacrylate, (c) from 0 to 35% by weight of at least one other ethylenically unsaturated copolymerisable monomer, in which the sum of (a), (b) and (c) totals 100%, and in which the aqueous polymer dispersion comprises, (d) from 10 to 55% by weight of an ionic tapioca starch, in which the weight of (d) is based on the total solids of components (a), (b), (c) and (d) of the aqueous polymer dispersion. The invention also relates to a process for the manufacture of the finely divided, starch containing aqueous polymer dispersions and also to the use of said finely divided starch containing aqueous polymer dispersions as a size for paper, board and cardboard.

Abstract: A finely divided, starch-containing polymer dispersion which is obtainable by free radical emulsion polymerization of ethylenically unsaturated monomers in the presence of at least one redox initiator and starch, wherein (a) from 0 to less than 40% by weight of at least one optionally substituted styrene, (b) from greater than 60 to 100% by weight of at least one C
1 -C
12 -alkyl acrylate and/or C
1 -C
12 -alkyl methacrylate, (c) from 0 to 10% by weight of at least one other ethylenically unsaturated copolymerizable monomer, are used as the ethylenically unsaturated monomers, the sum (a) + (b) + (c) being 100% and being based on the active monomer content and (d) from 15 to 40% by weight of at least one degraded starch which has a molar mass M
w of from 1000 to 65 000 g/mol, based on the total weight of solids content of components (a) + (b) + (c) + (d), are used as the starch, and the polymerization being carried out in the presence of at least 0.01% by weight, based on the monomers used, of at least one terpene containing chain-transfer agent, and in which the polymer dispersion optionally comprises an aluminium compound. The use of the finely divided, starch-containing polymer dispersions as sizes for paper, board and cardboard is also claimed.
