Abstract: A cycloolefin polymer moulding composition containing organophosphorus compounds of the formula IX R -[P(OR )2]n (IX), of the formula X or of the formula XI optionally in addition to other additives, exhibits improved stability to chemical degradation. The organophosphorus compounds used according to the invention preserve the melt viscosity of the moulding composition at the highest level (least deviation from the initial value). They also result in the best initial colours of the test specimens and in a smaller colour change after compounding (kneading) experiments.

Abstract: Copolymers (I) of olefinic monomer(s) comprise an isomeric mixt. of esters of isobornyl alcohol with an alpha , beta -unsatd. acid. The isomeric alcohol mixt. contains: (a) not more than 92% isoborneol, (b) at least 3.5% iso-fenchyl alcohol, and (c) at least 1% pseudo-bornyl alcohol. Also claimed are: (i) a process for the prodn. of (I) by bulk polymerisation in the presence of aliphatic azo cpds., diacyl peroxide, alkyl per-esters, alkyl hydroperoxide, dialkyl peroxide or peroxy-di-carbonate as radical initiators; and (ii) a process for the prodn. of water-dilutable polyacrylate dispersions by: (A) dissolution of (I) in a water-dilutable organic solvent, followed by: (B) partial or complete neutralisation, and (C) dilution by adding water or stirring the soln. into water.

Abstract: Low-viscosity copolymers with OH and COOH gps. (I) are obtd. by reacting (A) 3 - 50 wt.% glycidyl ester(s) of satd. aliphatic carboxylic acids with a tert. or quat. alpha -C atom and (B) 97 - 50 wt.% of at least 2 unsatd. comonomers, at least one of which contains at least one COOH gp. and at least one of which is sterically hindered, in the presence of radical initiators, and with an excess of COOH gps. in (B) wrt. epoxide gps. in (A) such that the prod. has an acid no. of at least 15 mg KOH/g. Also claimed is the above process for the prodn. of (I). Also claimed are 1-component paints with (I) as binder and formaldehyde/amino-resin reaction prods. (opt. etherated with 1 - 8 C aliphatic alcohol) as hardeners, and 2-component paints with (I) as binder and polyisocyanates or urethane-forming polyisocyanate derivs. as hardeners.

Abstract: Copolymers of particularly low viscosity, which can be prepared by a polymerization in bulk, in which one component (A) is initially charged and, in the further course of the polymerization, at least two olefinically unsaturated copolymerizable monomers (B) are added, of which at least one contains at least one COOH group and at least one is sterically-hindered are usefully employed in coating compositions.

Abstract: A glass-fibre-reinforced cycloolefin polymer material comprises from 1 to 99% by weight of at least one cycloolefin polymer, in particular a norbornene-ethylene copolymer, and from 99 to 1% by weight of glass fibres. The absolute value for the refractive index difference (refractive index of glass of glass fibres minus refractive index of cycloolefin polymer) is at most 0.015 for each cycloolefin polymer, and the refractive index of the glass fibres is in the range from 1.510 to 1.560. The materials have good mechanical properties and good light transparency. The glass fibres employed preferably contain no sizes.
