Statistic comb polymers, method for producing the same and their use

Statistic comb polymers obtainable by the radical copolymerization of a vinylic poly(alkylenoxide) compound (A) with an ethylenically unsaturated monomer compound (B) according to the catalytic chain transfer method (CCT). The comb polymers are extremely suitable for hydraulic binder suspensions based on cement, lime, gypsum and anhydrite as they have, for the same dosage, an improved water reducing power over conventional flow agents. The corresponding building material mixtures are characterized by a substantially reduced stickiness and plastic viscosity once said comb polymers are added, which dramatically improves the plasticity of very cement-rich building material mixtures, such as concretes. The building material mixtures using the inventive flow agents have a considerably increased slump flow and an increased shear-thinning behavior as compared to conventional concretes without the tendency to segregate.

RAIL VEHICLE WITH PRESSURE SURGE-SAFE GREYWATER LINE

The invention relates to a rail vehicle with a greywater line (5, 10, 11) which is connected to an area surrounding the rail vehicle directly or via a collection container (17). The greywater line (5, 10, 11) is equipped with a pressure protection valve, which protects a gray wire line (5, 10, 11) section upstream of the pressure protection valve from pressure surges occurring in the area surrounding the rail vehicle. The pressure protection valve is designed as a pinch valve (6) which is controlled by a control device (8) in order to protect the greywater line (5, 10, 11) section from pressure surges.

COPOLYMERS BASED ON UNSATURATED MONO- OR DICARBOXYLIC ACID DERIVATIVES AND OXYALKYLENEGLYCOL-ALKENYL ETHERS, METHOD FOR THE PRODUCTION AND USE THEREOF

The invention relates to copolymers based on unsaturated mono or dicarboxylic acid derivatives, oxyalkyleneglycol-alkenyl ethers, vinyl polyalkyleneglycol or ester compounds, in addition to the use thereof as additives for aqueous suspensions based on mineral or bituminous binding agents. Said invention is characterised in that the inventive copolymers, having a long lateral chain, impart small amounts of excellent processing properties to aqueous binding suspensions, and simultaneously, cause the water content in the concrete to be greatly reduced. Furthermore, the inventive copolymers cause, compared to prior art, dramatically increased early strength development which enables profitability, in particular in the construction of concrete, to be drastically increased. © KIPO & WIPO 2007 ...

Use of block copolymers as dispersants for aqueous suspensions of solids

The use of block copolymers which were prepared by polymerization of a poly(alkylene oxide) compound (A) with at least one ethylenically unsaturated monomer compound (B), as dispersants for aqueous suspensions of solids, in particular based on hydraulic binders, such as, for example, cement, lime, gypsum or anhydrite, is described. Surprisingly, these block copolymers have a substantially better water-reducing power at the same dose in comparison with conventional superplasticizers based on comb polymers. Moreover, the slump loss can also be reduced in comparison with conventional superplasticizers by modification of the adhesive block.
