    摘要: THERE ARE DISCLOSED SPARYABLE AND AEROSOLIZABLE WEBFORMING COMPOSITIONS FOR FORMING SELF-SUPPORTING, THREE DIMENSIONAL WEBS OF RANDOMLY ASSOCIATED, JOINED MONOFILAMENTS RANGING IN AVERAGE DIAMETER FROM ABOUT 1 TO 10 MICRONS, THE SPRAYABLE WEB-FORMING COMPOSITIONS COMPRISING A WATER-INSOLUBLE HYDROCARBON ELASTOMER, AT LEAST ONE WATER:INSOLUBLE RESIN OF HYDROGENATED ROSINS AND POLYOL ESTERS THEREOF, PHENOLIC RESINS, HYDROCARBON RESINS OR COUMARONE-INDENE RESINS COMPARTIBLE WITH SAID ELASTOMER, AND SOLVENT COMPARTIBLE WITH SAID ELASTOMER AND SAID RESIN, AND THE AEROSOLIZABLE WEB-FORMING COMPOSITION COMPRISING, IN ADDITION TO THE COMPONENTS STATED FOR THE SPRAYABLE WEB-FORMING COMPOSITIONS, A PROPELLANT INERT TO SAID ELASTOMER, RESIN AND SOLVENT. THE SPRAYABLE AND AEROSOLIZABLE WEB-FORMING COMPOSITIONS MAY CONTAIN ENCAPSULATED COMPONENTS, E.G., COLORING AGENTS, PERFUMES OR OTHER SCENTS, E.G., INSECT SEX ATTRACTANTS, AGRICULTURAL CHEMCALS, INSECTICIDES, ECT. A PLASTICIZER CAN BE INCLUDED IN THE AEROSLIZABLE FORMULATION TO IMPART INCREASED TACKINESS TO THE WEB OVER EXTENDED TIME PERIODS. THE WEB-FORMING POLYMER SOLUTIONS OR DISPERSIONS CAN BE DISPENSED FROM VARIOUS TYPES OF DISPENSING SYSTEMS AND EQUIPMENT, E.G. FROM SPARY GUNS, PORTABLE AEROSOL CANS, ECT. TO PROVIDE AN ADVANTAGEOUS WAY OF DISPENSING AGRICULTURAL TREATING AGENTS OR OTHER ENCAPSULATED MATERIALS ONTO PLANTS OR OTHER DESIRED REPOSITORIES OR LOCATIONS WITHOUT INTERFERING THEREWITH, E.G. WITH PLANT GROWTH OR METABOLIC PROCESSES THEREOF.

    摘要: 1,177,675. Pressure sensitive adhesive tapes. MORGAN ADHESIVES CO. 28 Feb., 1967 [13 April, 1966], No. 9467/67. Heading B2E. [Also in Division C3] A pressure sensitive adhesive tape comprises a backing having at least one coating of a composition comprising a mixture of from 90 to 50 parts by weight of a random block styrene-butadiene copolymer comprising a block of styrene-butadiene copolymer and a block of polystyrene, correspondingly from 10 to 50 parts by weight of a sequentially polymerised styrene-butadiene copolymer consisting of a central block of polybutadiene and two terminal blocks of polystyrene, and from 50 to 150 parts by weight of a resin which is compatible with said polymers and is at least partially soluble therein. Suitable resins include the pentaerythitol ester of hydrogenated rosin, other rosin derivatives, terpene resins, coumar one-indene resins, vinyl toluene -α-methyl styrene copolymer, fossil resin, ketone resins, and chlorinated polyphenyl. The composition may contain antioxidant, antiozonant, UV absorber, plasticiser, and filler and may be applied to the backing as a solution in an organic solvent.

    摘要: A NEW RUBBER COMPOSITION COMPRISING RUBBER REINFORCED BY DISTRIBUTING THEREIN CARBON FIBERS, CARBON BLACK AND SOFTENED IN COMBINATION RESPECTIVELY IN A PARTICULAR AMOUNT. THE SUITABLE AMOUNTS ARE 0.02 TO 0.10 VOLUME FRACTION OF CARBON FIBERS, 0.05 TO 0.25 VOLUME FRACTION OF CARBON BLACK AND 0.02 TO 0.30 VOLUME FRACTION OF SOFTENER. SUBSTANTIALLY UNIFORMLY DISTRIBUTED CARBON FIBERS, CARBON BLACK FINE PARTICLES AND FURTHER FINER SOFTENER PARTICLES DISPERSE THE CONCENTRATED STRAIN LOCALLY GENERATED IN THE RUBBER COMPOSITION TO EFFECTIVELY PREVENT THE SUDDEN DETERIORATION OF THE RUBBER ARTICLE WHICH PHENOMENON CAN BE OBSERVED IN SOME TYPES OF RUBBER. THUS THE VULCANIZED RUBBERS MADE OF SAID COMPOSITION HAVE HIGH RESISTANCE OF FATIGUE, ELONGATION, MECHANICAL STRENGTH AND ELASTICITY IN COMBINATION WHICH MAKES THEM VERY USEFUL FOR TIRES, CONVEYOR BELTS ETC. TO BE SUBJECTED TO SEVERE DYNAMIC CONDITIONS.

    摘要: Nonwoven fabrics that have excellent wet strength and dry strength are formed by adding to an aqueous suspension of natural and/or synthetic fibers a binder comprising (a) an anionic polymer latex and (b) a mixture of alkali metal salts of disproportionated rosin and fortified rosin, precipitating the binder on the fibers, and forming the treated fibers into a nonwoven fabric.
