Abstract:
Polymer dispersions are heat-sensitized by the addition of alkoxylated amines having inverse solubility, when the pH of the mixture is below 6.
Abstract:
O.Z. 0050/40286 Shaped articles are produced from a finely particulate material as aggregate and an aqueous binder preparation containing an acrylate polymer by moistening the aggregate with the binder preparation, making it into the desired shape and then drying it, using a binder preparation whose binder is an acrylate polymer whose glass transition range is relatively high and which is formed from (A) a predominant amount of methyl methacrylate, (B) a minor amount of (meth)acrylic acid, (C) a minor amount of an optional alkyl acrylate and (D) a small optional amount of another specific polymerizable compound.
Abstract:
O.Z. 0050/033671 of the disclosure: An improved paper-coating composition which contains, per 100 parts by weight of a finely divided pigment, from 5 to 25 parts by weight of a copolymer A, in the form of an aqueous dispersion, as a binder, and from 0.5 to 10 parts by weight of a copolymer B, containing (a) from 20 to 70% by weight of copolymerized units of hydroxy-C2-C4-alkyl acrylates or hydroxy-C2-C4-alkyl methacrylates, (b) from 10 to 50% by weight of copolymerized units of acrylic acid, methacrylic acid, maleic acid and/or monoesters of maleic acid and (c) from 5 to 50% by weight of copolymerized units of acrylonitrile, methacrylonitrile, C1-C4-alkyl acrylates or C1-C4-alkyl methacrylates, or vinyl esters of saturated C2-C4-carboxylic acids as the co-binder, with or without from 0.1 to 2.0 parts by weight of an optical brightener which is activated by the co-binder. The paper-coating composition has high water retention.
Abstract:
