Abstract: For the preparation of thermoplastic materials based on (a) homopolymers or copolymers of vinyl chloride and (b) polyacrylates having a glass transition temperature of less than -20.degree. C., firstly the acrylate is polymerized in aqueous emulsion in the presence of crosslinking compounds copolymerizable with the acrylates and having at least two nonconjugated double bonds. Secondly, the vinyl chloride or vinyl chloride with up to 20% by weight of copolymerizable monomers is heated with an initiator, a suspension agent system and optionally additives in an aqueous suspension to a temperature of about .gtoreq.30.degree. C. The polyacrylate is subsequently added and polymerization carried out at temperatures of about >30.degree. C. to the desired conversion. The resulting polymers exhibit improved particle size distribution, good reproducibility of the bulk density and in particular caked deposits on the wall are dramatically reduced during polymerization.

Abstract: A process for the production of a thermoplastic composition for molded parts having improved impact resistance, transparency, surface gloss, and weatherability, and formed of a hard inner core of crosslinked polystyrene, a rubber-elastic intermediate layer of crosslinked polyacrylic ester, and an outer layer of polyvinyl chloride, wherein the inner core thereof is produced by the steps of:(a) forming a mixture, before or after addition of an initiator, under polymerization conditions in the presence of an emulsifier, of 0.01-5.

Abstract: Polyesters are modified by adding an aqueous latex having a solids content of <50% by weight. The synthetic resin contained in the latex has a glass transition temperature of .ltoreq.0.degree. C. and contains 0.1-20 mol-% of functional groups.

Abstract: A method and an apparatus for making a fillet seam closure on folding boxes fabricated from box-board internally lined with aluminum foil and coated with a thermal plastic resin includes folding the fillet seam along a fold line, holding the areas of the fillet seam to be welded together by applying compressive forces along a line parallel to the desired weld seam and slightly spaced therefrom between the weld seam and the fold line and ultrasonically welding the fillet seam with a simultaneous application of pressure in the weld seam which gradually decreases from the weld seam center line to the edge facing the fold line to effect the displacement of the thermal plastic resin from the center line towards the edge in the formation of a V-joint. The weld is allowed to cool off and the compressor forces are maintained during the welding and the cooling operations.
