Copolymers of butadiene and styrene, alphamethyl styrene or styrene nuclearly substituted by a C 1  to C 4  alkyl group are made by copolymerizing a monomeric mix containing 10 to 98 parts by weight of butadiene per 100 parts of monomer, in the presence of a lithium-based catalyst e.g. butyllithium, at a temperature in excess of 310‹ F. whilst having present sub stantial amounts of the monomers whereby there is produced a copolymer having less block polymer of the styrene-type than would be produced by copolymerizing at 115‹ F. and otherwise identical conditions. An ether-type compound may be incorporated into the polymerization system. The copolymerization may be carried out in bulk, or in a hydrocarbon solvent and by batchwise or continuous techniques e.g. using two reactors. The product may be a liquid. Microstructures of the butadiene unit of the copolymer are given. The copolymers may be blended with natural or synthetic rubbers or with polystyrene or polypropylene to form high impact materials, and sulphurvulcanized in presence of carbon and plasticizers.

Title: Marine seismic exploration system
IPC: G01V1/38
Filed: 1965-10-25
Abstract: 1,090,428. Seismic prospecting; semi-conductor pulse circuits. TEXAS INSTRUMENTS Inc. Oct. 25, 1965 [Dec. 24, 1964], No. 45143/65. Headings H3T and H4D. In a marine seismic exploration system for enabling normal moveout corrections to be applied to the output signals of a group of detectors spaced along a towing member, the spacings between a shot-point and selected detectors are determined by recording signals representing the time of reception of the " first break energy " at the selected detectors. In the Fig. 1 embodiment the outputs of towed detectors 31 to 54 are amplified at 59, sampled and converted to digital form by multiplexer and analogue-to-digital converter 89, and magnetically recorded on tape 91. A timebreak (shot instant) signal, transmitted via a radio link 57, is also recorded on tape 91. The outputs of selected detectors 31, 35, 40, 45, 50, 54 are applied to signal channels 101 to 106, in each of which the " first break " signal, i.e. that due to the direct travel of acoustic energy through the water from shot-point 20 to the detector location, is detected by virtue of its high amplitude and high frequency relative to the predominant frequency of the seismic signal and is converted to an elongated pulse. The elongated pulses are then applied to converter 89 and subsequently recorded on tape 91, their duration exceeding the multiplexer sampling interval so that the first break times are reliably indicated. Tape 91 is subsequently processed by computer and normal move-out corrections for all the detector positions 31 to 54 are derived by interpolation from the first break times for detectors 31, 35, 40, 45, 50, 54. In each first break signal channel (detailed in Fig. 2) the detector signal is applied to an amplifier (120, 122, 123, 130) having a lower cut-off frequency about one octave above the predominant frequency of the seismic signal. The high-frequency first break signal passes to output (133) to provide a conventional wiggletrace recording, and is also applied to stages (163, 165) which develop by integration on capacitor (171) a voltage which blanks off stage (130) so that only the initial part of the first break signal passes stage (130). This initial part triggers transistor (139), thereby firing silicon-controlled rectifier (148) to discharge capacitor (149) and provide an elongated pulse at terminals (155, 157) for application to the analogue-to-digital converter 89 (Fig. 1). Capacitor (149) recharges through resistor (151) when the circuit through gate (142) is closed in response to a time-break signal.
