Abstract: Aq resin dispersions are claimed which comprise: (A) 20-50 wt.% of a resin obtd. from (a) 0.5-10 wt.% of a substd. acrylamide monomer of formula (I) or (II); (b) 25-99.5 wt.% of an ester of (meth)acrylic acid with a 1-18C alcohol; (c) 0-60 wt.% of one or more vinyl aromatic monomers and/or other unsatd. hydrocarbons; and (d) 0-8 wt.% of other comonomers; (B) an emulsifier; (C) 0-60 wt.% of one or more inorgn. fillers; (D) 0-15 wt.% of one ore more external plasticisers; and (E) at least 10 wt.% of water as the residue of the compsn.. R1= H or Me; and R2 = -C2H4- or -C3H6-. USE/ADVANTAGE - The use of the dispersion is claimed in coating, bonding, sealing, colouring or impregnating. Concrete roofings coated with a film of the dispersion are specifically claimed. The dispersions give better film solvent resistance than do those of EP-211432.

Abstract: For moulded bodies, obtainable by impregnation or coating of base mouldings built up mainly from mineral fibres, non-fibrous mineral fillers and starch, with compositions which contain, as binders, copolymers consisting of a) 60 to 95 % by weight of methyl methacrylate (monomer I> b) 5 to 40 % by weight of acrylate and/or methacrylic acid (monomers II> c) 0 to 35 % by weight of one or more acrylates of a C1- to C8-alkanol (monomers III> d) 0 to 5 % by weight of copolymerisable, olefinically polyunsaturated monomers (monomers (IV) and e) 0 to 5 % by weight of other copolymerisable monomers (monomers V) in the polymerised form, the proportions by weight of the monomers I, II, III and V are selected within the indicated limits in such a way that a polymer built up only from these monomers would have a glass temperature of from 60 to 125 DEG C.
