Abstract: Polymer composition suitable for ABS styrenic resin replacement where high dimensional stability and a good esthetical appearance is required, comprising a polymer blend (A), comprising 60-80% by weight, of a crystalline propylene homo or copolymer (A1) (MFR <50 g/10 min); and 20-40% by weight, of copolymer(s) of ethylene (A2). Said polymer blend (A) having values of MFR up to 30 g/10 min; the amounts of (A1) and (A2) being referred to the total weight of the polymer blend (A). The polymer composition further comprises 20-40% by weight, of a talc mineral filler (B); the amount of components (B) being referred to the total weight of the composition. Optionally the polymer composition further comprises 1-15% by weight, of an elastomeric polymer (C) different from (A2), having a hardness (Shore A, ASTM D-2240) value equal to or lower than 80 points; the amount of components (C) being referred to the total weight of the composition.

Abstract: The invention relates to a glass fiber-reinforced molding composition composed of an olefin polymer, in particular a propylene polymer. The molding composition comprises an olefin polymer which contains 5-50% by weight of glass fibers which are bonded to the olefin polymer by means of a compatibilizer, and from 10?4 to 1% by weight, preferably from 10?3 to 10?1% by weight, of a phthalocyanine pigment as the nucleating agent. The low costs and the fact that even a very small fraction of the phthalocyanine pigment in the polymer leads to sufficient nucleation ensures extremely inexpensive production. The nucleation with the phthalocyanine pigment leads to an improvement in the impact strength, and also in the yield stress and tensile strain at break of the molding composition.

Abstract: A polypropylene molding composition which comprises, as the reinforcing substance, a clay mineral of specific composition shows an improved profile of properties compared with known polypropylene molding compositions reinforced with talc. The impact strength of molding compositions which have not been finished with impact modifiers increases considerably, while the strength, in particular the ball indentation hardness, of molding compositions finished with impact modifiers increases. Generally, an improvement in scratch resistance and surface quality is to be observed compared with molding compositions reinforced with talc.

Abstract: Switching and display elements based on ferroelectric liquid-crystals often exhibit a pronounced optical hysteresis which results in the appearance of so-called ghost images. This phenomenon can be markedly reduced or even suppressed if at least one of the two orienting layers are in direct contact with the electrodes and is composed of an electrically conductive polymer of the formula (I): ##STR1## in which R.sup.1, R.sup.2 =independently of each other, H, or straight-chain or branched alkyl or alkoxy containing 1-16 carbon atoms, or halogen,X=S, NH,Y.sup.- =BF.sub.4.sup.-, PF.sub.6.sup.-, PO.sub.4.sup.3-, AsF.sub.6.sup.-, SbCl.sub.6.sup.-, SO.sub.4.sup.2-, HSO.sub.4.sup.-, alkyl--SO.sub.3.sup.-, perfluoroalkyl--SO.sub.3.sup.-, aryl--SO.sub.3, F.sup.- or Cl.sup.-, andn is an integer from 4 to 100 andm is an integer from 1 to 30.

Abstract: In electrically conducting polymers in their oxidized (doped) form, which are known per se, the anions can be exchanged in any desired manner, if the polymer in solution is brought into contact with a salt containing the anion to be exchanged and the solution equilibrium is established, taking account of the solubility product of the salts present. In this manner, the properties of the electrically conducting polymers can be adapted to different purposes.
