摘要:
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 50° C., wherein respecting the copolymerization of comonomers M1 with comonomers M2, the copolymerization parameters r1 2.0, and wherein some or all of comonomers M2, and at least 3% by weight are introduced before the start of the polymerization.
摘要:
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.
摘要:
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.
摘要:
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.
摘要:
Silicone-modified polymers of ethylenically unsaturated monomers are prepared in the form of aqueous polymer dispersions or water-redispersible polymer powders, by A) preparing a prepolymer by means of polymerization of one or more ethylenically unsaturated monomers and at least one ethylenically unsaturated silicone macromer and isolating the prepolymer, B) dissolving the prepolymer in one or more ethylenically unsaturated monomers, C) emulsifying this solution in water and polymerizing by a free-radical mechanism, and optionally D) drying the resulting aqueous dispersion of silicone-modified polymers.
摘要:
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.
摘要:
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.
摘要:
A method and a system for transmitting data from a first data processing device to a second data processing device, wherein the first data processing device has a display device. The second data processing device generates an encrypted input mask and transmits it to the first data processing device which displays it. The encrypted input mask is decrypted by being viewed through an optical filter having a decryption pattern, and the data to be transmitted are input to the first data processing device using the input mask that has been decrypted by the optical filter and are transmitted to the second data processing device.
