Abstract: Silicone-containing addition polymers having numerous uses are prepared by polymerizing addition polymerizable monomers in the presence of a silicone-containing polyvinyl alcohol, and/or by adding a silicone-containing polyvinyl alcohol to an aqueous addition polymer dispersion prior to spray drying, the silicone-containing polyvinyl alcohol containing at least one polymerizable group.

Abstract: Non-blocking solid vinyl ester copolymer resins have at least two different glass transition temperatures and are prepared by free-radical bulk or solution polymerization of 1. a) 50% to 97 % by weight of one or more comonomers M1 selected from vinyl esters of optionally branched C1-15 alkylcarboxylic acids and optionally alpha-olefin(s), monomers M1 producing homopolymers with a Tg<40° C., with b) 3% to 50% by weight of one or more comonomers M2 selected from vinylaromatics, (meth)acrylic acid and esters or amides thereof, and acrylonitrile, the comonomers M2 producing homopolymers having a Tg>50° C., wherein respecting the copolymerization of comonomers M1 with comonomers M2, the copolymerization parameters r1<0.2 and r2>2.0, and wherein some or all of comonomers M2, and at least 3% by weight are introduced before the start of the polymerization.

Abstract: Polymer dispersions of polymers derived from silicone macromers and ethylenically unsaturated monomers are capable of incorporating large amounts of chemically bonded macromer, when the silicone macromer and part of the unsaturated monomer are polymerized in aqueous medium as an initial charge with an oil soluble initiator, and the remaining monomers are fed in and polymerized using a water soluble initiator. The dispersions may be dried to form water redispersible polymer powders.

Abstract: The present invention relates to a method and a system for initiating and/or conducting a transaction that is associated with at least two corresponding declarations of intent, in particular a payment transaction, between at least two transaction parties via a processing unit (3), in which payment transaction at least one of the transaction parties uses a land line telephone or mobile telephone (1, 2) or a mobile communications device for transmitting data. The method is characterized by the transmission of data to the processing unit by at least two transaction parties within a limited time frame, and by the fact that the initiation of the data transmission of these transaction parties is effected actively by the transaction parties and not by the processing unit (3), while the data transmitted during initiation contain features that enable correlating the declarations of intent with one another.

Abstract: Silicone-containing polymers having numerous uses are prepared by polymerizing one or more ethylenically unsaturated monomers in the presence of a branched organopolysiloxane having at least one lipophilic branched siloxane portion and at least one optionally branched hydrophilic portion.

Abstract: Silicone-containing addition polymers having numerous uses are prepared by polymerizing addition polymerizable monomers in the presence of a silicone-containing polyvinyl alcohol, and/or by adding a silicone-containing polyvinyl alcohol to an aqueous addition polymer dispersion prior to spray drying, the silicone-containing polyvinyl alcohol containing at least one polymerizable group.

Abstract: The present invention relates to a locking device 2 for objects of use, which are to be used for a particular period of time by a user, whereby the locking device 2 opens after the input of an opening code 4. The locking device is distinguished in that after input of an end code 6 the locking device issues a confirmation code (8) and changes the opening code in a particular manner (4.fwdarw.4'). Further, the invention relates to a method for the controlled, time-restricted, use of objects of use, which employs the locking device 2. In this method, an opening code 4 is issued by an access control unit 1, the opening code 4 is input into the locking device 2 for opening the same, an end code 6 is input for ending the use and then a confirmation code 8 is issued, the opening code being altered (4.fwdarw.4') by means of the locking device 2.
