    摘要： A method for lowering the residual monomer content of non-vitrified processing aids for thermoplastic polymers involves subjecting an emulsion polymerizate containing methylmethacrylate and, optionally, up to 50% by weight of a comonomer to a post-catalysis step to reduce the residual monomer content followed by a spray-drying step where the residual monomer content is further reduced. The spray-drying step is performed at an exit temperature which is either above the boiling point of methylmethacrylate or if an optional comonomer is present which has a higher boiling point than methacrylate, at a temperature above the boiling point of the comonomer. The resulting product which is suitable for use as a non-vitrified processing aid has a residual monomer content of 100 ppm or less. The processing aid can be used with thermoplastics to form containers, e.g., beverage bottles of PVC, which would not adversely affect odor or taste of the contained food product.

    摘要： Polyoxymethylene with improved acid stability, process for production and use thereof. By adding 0.01 to 5 parts of an alkali metal salt of a polybasic acid, for example oxalic acid, citric acid and/or 0.01 to 5 parts of a polyalkylene glycol, for example polyethylene glycol and/or 0.1 to 100 parts of a thermoplastic polyurethane, each related to 100 parts of a polyoxymethylene, this polymer is stabilized against attack by acids, wherein in particular the combination of an alkali metal salt, in particular an oxalate, with small proportions of a thermoplastic polyurethane is advantageous. The proportion of thermoplastic polyurethane may be reduced when the thermoplastic polyurethane has a Shore A hardness of 70 to 96. The weight loss of a stabilized POM under the action of acid may be less than 3% of that of an unstabilized POM. The products are useful when exposed to acidic agents such as irrigation systems, dishwashers, sanitary installations.

    摘要： A processing agent for polyvinyl chloride and other thermoplastic polymers. The processing agent is a copolymer which contains a monomer whose homopolymer has a T.sub.g .gtoreq.65 C. and contains 3 to less than 75% by weight of a comonomer which has a C.sub.8 -C.sub.22 alkyl component. The alkyl component should be apportioned in such a fashion that the transmission of the copolymer in ethyl acetate is at least 90% in the case of a 10% solution.

    摘要： A detergent composition with improved dirt-suspending power, method for its production and use of a suitable polycarboxylate for this purpose. The novel detergent contains, in addition to the customary components such as surfactant, calcium-binding silicate, etc., at least 1% by weight of a polycarboxylate with the schematic structure (X, Y, Z) in which X stands for ##STR1## Y for ##STR2## and Z for--(F).sub.q --.These carboxylates can be produced from acrolein and optionally one or several comonomers by means of oxidizing radical donors without saponifying conditions and/or without subsequent Cannizzaro reaction. The novel detergents exhibits improvements over traditionally used co-builders in all essential detergent qualities. The carboxylates may be used in detergents, fine-fabric detergents, color detergents, liquid detergents and compact detergents.
