Abstract: Manufacture of calendered sheeting of thermoplastic materials, particularly polyvinyl chloride, which is free from flow lines. The calendered web of plastics material, on passing from the penultimate calender roll to the final calendar roll, is cooled by passing over smaller guide rolls. The resulting calendered sheeting may be used for the usual purposes, especially in packaging.

Abstract: The invention relates to a moulding composition which is a mixture of two polymers A and B of vinyl chloride. Polymer A is a homopolymer or copolymer of vinyl chloride having a K value of from 55 to 65 and makes up from 99.9 to 95 % by weight of the moulding composition. Polymer B is present in a proportion of from 0.1 to 5 % by weight and is prepared in emulsion by a batch process, has a mean particle diameter (d50 value of the primary particles) of 0.02 to 1.0 mu m and has a K value of from 75 to 90. The moulding composition may contain conventional graft copolymers based on crosslinked or uncrosslinked rubbers or additives and is used for the production of films.

Abstract: The invention relates to a method for producing ethyldimethylamine and triethylamine, comprising the steps of (i) reacting a mixture from diethylamine and dimethylamine with ethylene in the presence of a catalyst from the group of the alkali metal dimethylamides, alkali metal diethylamides and alkali metal hydrides, (ii) removing the catalyst, (iii) separating by distillation the obtained mixture into triethylamine and ethyldimethylamine and optionally diethylamine and dimethylamine, (iv) optionally returning the catalyst and the educt amines to the reaction. The inventive method allows the coupled production of ethyldimethylamine and diethylamine in a simple process.

Abstract: A vinyl chloride emulsion polymer (I) esp. for film prepd. according to the Luvitherm process contains 0.5-5 wt. % graft copolymer (II) as processing aid. (II) comprises (a) 30-80 wt.% elastomeric polymer as the backbone with a Tg 0 degrees C and contains >=15 wt.% (w.r.t. the elastomeric backbone) conjugated diene and (b) 70-20 wt.% 1-4C alkyl methacrylate and/or monovinyl aromatic cpd. and opt. other comonomers. The PVC may be processed more rapidly into a film. The films have good gloss and smoothness and may be used as adhesive or magnetic recording tapes.

Abstract: The invention relates to a moulding composition which is a mixture of a graft copolymer A and PVC. The graft copolymer A makes up 70-95 % by weight of the moulding composition and contains a monomer from the group consisting of vinyl aromatic monomers and the group consisting of ethylenically unsaturated monomers, grafted on to a rubber from the series consisting of polybutadienes, polyacrylates or EPDM. Component B is present in the moulding composition in a proportion of 5-30 % by weight and is a polymer of vinyl chloride prepared by a batch method and having a Fikentscher K value of 75-90 and a mean particle diameter (primary particles) of a) 0.02-1.0 mu m (emulsion polymer) or b) 0.1-2.0 mu m (micro suspension polymer). The moulding composition may additionally contain conventional additives and is used for the preparation of mixtures with polyvinyl chloride.

Abstract: The films are produced by calendering a PVC mix. contg. pref. 0.1 - 3 wt.% blowing agent in a first stage at a temp. below the activation pt. of the blowing agent and in a second stage at a temp. above this pt. Pref. the temps. are 150 - 180 degrees C and 210 - 250 degrees C resp. The foamed films produced have good tear resistance and mechanical strength and are used for packaging/insulation and as pressure sensitive carriers.
