Title: Alkyl-sulfoxide and alkyl-sulfone terminated oligomers of ethylenically unsaturated monomers
IPC: C08F2/38
Filed: 1969-11-07
Abstract: 1283087 Sulphoxide and sulphone terminated oligomers; emulsion polymerization processes UNIROYAL Inc 7 Nov 1969 [19 Nov 1968] 54636/69 Heading C3P Oligomers having the formula are prepared by oxidizing an oligomer of the formula In the above formulµ R represents an alkyl group (primary, secondary or tertiary) having from 5-20 carbon atoms, R 1  and R 3  are each H, methyl, ethyl or -COOH, R 2  and R 4  are each H, methyl, ethyl, -COOH or -CH 2 COOH, Y is a strongly hydrophilic group selected from -COOH, -CONH 2 , -OCH 3 , -OC 2 H 5 , -CH 2 OH and X is either a group as defined for y or is a less hydrophilic group selected from -COOC 2 H 4 OH, a+b is from 2 to 50, and a/a+b is from 0 to 1 unless X is a said less hydrophilic group in which case a/a+b is less than 0À6, and n is 1 or 2. (Alkyl sulphide-terminated oligomers similar to those used as starting material are described in Specification 1,207,532.) Oxidation of the oligomers is suitably effected, generally in an aqueous medium, with hydrogen peroxide or ozone, e.g. at 30-90‹ C.; one mole equivalent of oxidizing agent yields the terminal sulphoxide derivative and two mole equivalents yields the corresponding sulphone. The new oligomers are soluble in water or can be rendered soluble in water (when they contain acidic groups) by conversion to salts, e.g. ammonium, substituted ammonium, alkali metal, alkaline earth metal and Group III metal salts. Monomers from which the oligomers are derived include acrylic acid, acrylonitrile, acrylamide, itaconic acid, methacrylic acid and methacrylamide. Oligomerization of the monomers is suitably effected in the presence of an appropriate mercaptan R-SH in an organic solvent, e.g. methanol or isopropanol, using as initiator ammonium persulphate, lauroyl peroxide or lauroyl peroxide/dimethyl aniline. The new oligomers are useful as emulsifiers in the emulsion polymerization of ethylenically unsaturated monomers, e.g. butadiene, butadiene-styrene, butadiene-acrylonitrile, butadiene vinylidene chloride, butadiene-methacrylonitrile (and corresponding monomer(s) in combination with a small amount of an unsaturated acid monomer, e.g. itaconic acid), styrene, styrene-acrylonitrile, styrene-methacrylonitrile, ethyl acrylate, ethyl acrylate-vinyl acetate, ethyl acrylate-methyl methacrylate, ethyl acrylate-styrene, ethyl acrylate-butyl acrylate, butyl acrylate-acrylonitrile, and combinations of an ester such as ethyl or butyl acrylate with a minor amount of a mixture of (a) styrene, methyl methacrylate, butyl acrylate or vinyl acetate with (b) acrylic, methacrylic or itaconic acid. In examples the monomers used are (a) butadiene, styrene and itaconic acid, and (b) styrene and acrylonitrile; in addition to the oligomeric emulsifiers used, other components present include potassium persulphate, tetrasodium salt of EDTA and t-dodecyl mercaptan.

Abstract: 1277604 Inductive signalling; transponders FERRANTI Ltd 21 Sept 1970 [11 Nov 1969] 55048/69 Headings H4L and H4U A means for automatically determining the position of each one of a plurality of objects within a given area, comprises a number of inductive loops together dividing the area into separate regions, means for applying to each loop a plurality of groups of coded signals, a transponder located with each object and responding only to a predetermined one of the coded signals and receiving means responsive to the signal from the transponder to indicate the identity of the object and the region within which it is located. As described, each group of signals consists of a transponder address signal followed by a loop identifying signal and the objects to be identified are located in a warehouse which is subdivided into four regions, each surrounded by an inductive loop, Fig. 1 (not shown). Each loop is fed via its own amplifier with a low-frequency carrier modulated with the coded signals under the control of a common control unit and each object carries a transponder receiving signals from an inductive loop and transmitting a modulated radio-frequency carrier as a response signal which is received and identified by a radio receiver. In operation, initially switches S1 to S4 of the control unit are in the position shown and a pulse code generator 58 which produces a repeated sequence of address codes, supplies the address code of one of the transponders to modulators 52 to modulate a low frequency carrier from 51 for transmission to the loops via amplifiers 53. This signal is received by the transponders, Fig. 3, and detected at 62, a unit 63 in the appropriate transponder recognizing the address signal and operating a switch 65 to connect the detector 62 to the transmitter modulator 67 for a predetermined period. The control unit 59 at the interrogator then changes over the switches S1 to S4 and causes the code generators 54 to 57 to supply loop identifying signals to the respective loops 21 to 24 to which only the transponder prepared by the preceding address signal will respond by retransmitting the corresponding loop identifying signal. This signal is received by the common radio receiver which may have a display panel or print-out indicating the location of each transponder. The loops may be energized one at a time instead of simultaneously to avoid difficulties when a transponder is located at the boundary between two loops.
