AN HYDROXYLATED ALPHA-OLEFIN-NON-CONJUGATED DIENE POLYMER HAVING HYDROXYL SUBSTITUTED SIDE CHAINS CONTAINING ONE HYDROXYL GROUP EACH AND OTHER SIDE CHAINS CONTAINING ETHYLENIC UNSATURATION AND A PROCESS FOR MAKING.
摘要:
TERMINALLY REACTIVE POLYMERS ARE PRODUCED BY OZONIZING HIGH MOLECULAR WEIGHT POLYMERS OF BRANCHED CONJUGATED DIOLEFINS SUCH AS ISOPRENE AND REACTING THE OZONIZED PRODUCTS WITH MODIFYING COMPOUNDS SUCH AS HYDRAZINE, HYDROXYLAMINE AND DIHYDRAZINO COMPOUNDS. THE REACTIVE POLYMERS ARE LOW MOLECULAR WEIGHT MATERIALS HAVING TERMINAL HYDRAZONE, OXIME AND HYDRAZOLE GROUPS; THEY REACT WITH POLYFUNCTIONAL COMPOUNDS SUCH AS DIISOCYANATES OR EPOXY RESINS TO FORM CROSS-LINKED STRUCTURES.
摘要:
AQUEOUS COMPOSITIONS THAT ARE SUBJECT TO DECOMPOSITION AND SPOILAGE BY THE ACTION OF BACTERIA ARE PRESERVED BY INCORPORATING IN THEM A SMALL AMOUNT OF A COMPOUND HAVING THE STRUCTURAL FORMULA
1-((CH2)M=N-CH2-),3-Y,(X)N-1H-INDAZOLE
WHEREIN X REPRESENTS HALOGEN, NITRO, ACOYLAMINO, AROYLAMINO, (HALOBENZYLIDENE)AMINO, OR METHYLENEIMINO; Y REPRESENTS HYDROGEN, HALOGEN, ACOYLAMINO, OR METHYLENEIMINO; M IS A NUMBER IN THE RANGE OF 4 TO 8; AND N IS A NUMBER IN THE RANGE OF ZERO TO 4. ILLUSTRATIVE OF THESE COMPOUNDS ARE N-(5,7-DICHLOROINDAZOLYL - N1 - METHYL) PIPERIDINE AND N-(3-CHLORO-5-NITROINDAZOLYL-N1-METHYL) HEXAMETHYLENEIMINE.
摘要:
A coloring composition for line- or pattern-drawing elements which comprises as a base material thereof one or more acidic sublimating substances such as benzoic acid, salicylic acid and phthalic acid. Lines and/or patterns drawn with the coloring composition are easily erased by heating.
摘要:
Brominated isoolefin polymers are ozonized in solution to yield flowable bromine-containing polymers of an isoolefin which may be cured with polyfunctional curing agents.
摘要:
A solid rubber golf ball is disclosed. The golf ball is made from a composition comprising polybutadiene and an unsaturated carboxamide cross-linking said polybutadiene with hydrogen bonding.
摘要:
A vulcanized composite laminate comprises a first layer of compounded EPDM rubber and a second compounded layer of butadiene-styrene rubber, a polybutadiene rubber or a blend of polybutadiene rubbers. The layers are bonded by depositing between them, prior to vulcanization, a graft copolymer consisting of an ethylene-propylene-ethylidene norbornene copolymer onto which has been polymerized butadiene and styrene; and a method of forming such composite rubber laminates.
摘要:
A water-based pigment ink contains a pigment, a hydrophilic dispersant, an aqueous medium, an alkali agent for solubilizing the hydrophilic dispersant in the aqueous medium, and a hydrophilic compound having at least one structural unit of “hydrophobic molecular chain-hydrophilic molecular chain-hydrophobic molecular chain” in a structure thereof. The water-based pigment ink is suited especially as an ink for ink-jet printers.
摘要:
Natural graphite-reinforced, cyclized butadiene elastomers are prepared by mixing a homopolymer or copolymer of butadiene and a monoolefinic monomer with natural graphite, curing this mixture with an organic peroxide or mononuclear quinone and thereafter cyclizing the cured mixture by heating at a temperature of 350*700*F. The natural graphite-reinforced, cyclized butadiene polymers are hard, infusible, thermoset materials which have outstanding physical properties, particularly modulii, and resistance to air oxidation, inorganic acids and other chemicals, and overall aging at elevated temperatures.
