Abstract: O.Z. 0050/033,922 A liquid-crystalline polymer phase having an induced cholesteric structure comprises a component having a chiral structure and a component having a nematic structure and contains a polymer with nematogenic units of the formula , wherein R1 is hydrogen or methyl, n is an integer from 1 to 6 and R3 represents specific structural elements containing at least two phenylene groups. Preferred is a copolymer comprising a component of the above formula and an additional chiral component of similar structure, prepared by copolymerisation of the nematogenic monomer with the chiral monomer. The liquid-crystalline polymer phase permits variation of the wavelength of the reflected light .lambda.R, and its cholesteric structure can be converted to the glassy polymer state and remains preserved in the solid state. Such liquid-crystalline polymer phases can be used in integrated optics, opto-electronics and information storage, e.g. for the manufacture of polarization filters or selective reflectors.

Abstract: A method is claimed for using cationically stabilised aq. polymer dispersions (PD) as binders for moulded prods. based on finely divided materials with a negative surface charge (M). These dispersions contain (A) a dispersed copolymer (A) with a static Tg of 40-110 deg. C, based on (a) 30-80 pts. wt. styrene, (b) 20-70 pts. wt. (1-8C alkyl) (meth)acrylate(s) and (c) 0-10 pts. wt. other radically copolymerisable monomers, and (B) as dispersant, a mixt. of prim., sec. and/or tert. organic mono-amine(s) with at least 8 C atoms and acid addn. salts thereof. Also claimed are (i) polymer dispersions (PD) as above; (ii) moulded prods. based on materials (M) and binders (PD); (iii) rectangular moulded sheets based on (M) and (PD), with a length and breadth of 30-70 cm and a thickness of 1-20 mm; (iv) a process for the prodn. of mouldings (ii), by suspending material (M) in water, adding dispersion (PD), precipitating copolymer (A) onto material (M) by adding bases or salts of multivalent anions, placing the mixt. obtd. in a mould, removing water, and drying; (v) moulded prods. obtd. by this process.
