Abstract: A 1,2-diphenylethylene/styrene copolymer (I) is prepared by polymerization of (A) 1,2-diphenylethene, (B) styrene and optionally (C) copolymerizable monomers whereby (A) and a polymerization initiator are mixed and component (B) and optionally (C) are continuously dosed into the reaction mixture. A 1,2-diphenylethylene/styrene copolymer (I) is prepared by polymerization of: (A) 1-63wt.% 1,2-diphenylethene, optionally substituted by up to 5 1-12C alkyl groups on the aromatic rings; (B) 37-99 wt.% styrene, optionally substituted by up to 5 1-12C alkyl groups on the aromatic ring; and (C) 0-50 wt.% copolymerizable monomers. whereby (A) and a polymerization initiator are mixed and component (B) and optionally (C) are continuously dosed into the reaction mixture.

Abstract: This method of noise suppression at industrial plants involves cutting down the amount of contact between the material in question and the pipe way or the tank into which it is being transported. If the resulting contact noise is then damped down by damping the humming effect that happens during material e.g. grain, flowing down the pipe, the overall noise effect will be reduced. The pipes and receiving tank could be lined with elastic material to reduce the vibrations. Also, the pipe ways may incorporate angles of less than 90 deg , ideally 30 to 60 deg which would reduce vibrations too. Use/Advantage - The technique is used when granular material is fed down a pipe into containers. The advantage is that the method suppress noise emissions from the movement of loose material through pipes into containers and dampens any humming noises.

Abstract: The noise damping, flexible cover layer is pressed, or secured, onto the noise emitting pipeline etc. in fastening section, forming only a fraction of the covered surface. The compression etc. is carried out in individual punch-form, line and/or face sections. Pref. at least one more noise damping layer is deposited over the first applied one and secured in the same manner. The application is typically such that the two layers enclose one or more cavities. The pipeline sections may carry spacers also covered by noise damping layers.

Abstract: Preparation of impact-modified polyvinyl chloride molding composition involves polymerisation in the presence of an acrylic ester rubber dispersion, giving improved plasticizers content. Production of impact-modified PVC molding composition comprises suspension polymerizing vinyl chloride (VC), optionally with comonomers, in the presence of acrylic ester rubber dispersion obtained by dispersing acrylic ester monomers, and optionally comonomers, in water to give droplets of average diameter 0.1-25 mu m in the presence of a protective colloid and optionally emulsifiers and then polymerizing using radical initiators. An Independent claim is included for the obtained compositions containing 2-12 pts. wt. acrylic ester rubber per 100 pts. wt. PVC.
