Moulding compound with flattened surface

Thermoplastic moulding materials contg. (A) 60-99 wt% of a thermoplastic polymer; (B) 1-40 wt% of a different thermoplastic polymer made up of units derived from (b1) 8-80 wt% (2-20C alkyl) acrylate, (b2) 8-80 wt% (meth)acrylonitrile and (b3) 0-80 wt% other comonomers; (C) 0-40 wt% fibrous and/or particulate fillers; and (D) 0-20 wt% additives and processing aids.

Paper pulp sizing - with aq dispersions contg reactive monomer with no salts

Paper fibres are bonded in absence of metallic salts at pH 5-9 pref. 6-8 using anionic polymer dispersions by polymsn. with a hydrophobic monomer in aq. medium in presence of emulsifiers contng. COOH gps., where the dispersions contain particles of mean size 200 nm and having Tg. 70 degrees C. Monomers are e.g. (meth)acrylic acid esters with >3C alcohols, or vinyl aromatic cpds. Emulsifiers are salts of (iso) fatty acids or resinic acids and their hydrogenation/disproportionation products or ethylene or diene reacted with maleic acid derivs. The process prevents growth of algae and deposits of adhesive and foaming. Corrosion is also reduced because the soln. is at near neutral pH in absence of salts.

GLASS FIBER REINFORCED POLYAMIDE MOLDING COMPOUNDS WITH HIGH IMPACT RESISTANCE

Production of mouldings based on a particulate additive, and a binding agent containing an acrylate polymer

The invention relates to the production of mouldings based on a particulate material as additive and an aqueous binding agent containing an acrylate polymer, the additive being moistened with the binding agent, converted into the desired shape and subsequently dried, characterised in that a binding agent is employed whose binder is an acrylate polymer whose glass transition range is relatively high and which is built up from (A) predominantly methyl methacrylate, (B) a minor amount of (meth)acrylic acid, (C) if desired, a minor amount of an alkyl ester of acrylic acid and (D) if desired, a small amount of other specific polymerisable compounds.
