摘要:
Processes for chemical functionalization of materials are described. The processes generally include chemical reaction between a thiol group of a first compound or material and an alkene group or alkyne group of a second compound or material. Also disclosed are functionalized materials and compounds suitable for functionalizing a material.
摘要:
A reinforcing cord 10 for rubber reinforcement of the present invention includes a reinforcing fiber 11. A coating film 12 is formed on a surface of the reinforcing fiber 11. The coating film 12 includes, as its main components, a rubber having acrylonitrile as one of its raw materials and a compound containing an oxazoline group. A method of manufacturing a reinforcing cord for rubber reinforcement of the present invention includes (i) applying an aqueous mixture including, as its main components, a rubber latex having acrylonitrile as one of its raw materials and a compound containing an oxazoline group onto a reinforcing fiber, and (ii) drying the applied aqueous mixture to form a coating film on the surface of the reinforcing fiber.

摘要:
A cyanoresin polymer is described, wherein about 10 percent to about 60 percent of the side chains on the polymer include a cyano group; and substantially all of the remaining polymer side chains include a hydroxyl group. A method of forming such a cyanoresin polymer is described. A capacitor having a dielectric film including such a cyanoresin polymer is also presented.
摘要:
Modified wool having improved shrink-proofing property is obtained by a two step process in which raw material wool is first immersed in a first aqueous bath containing a water-soluble organic phosphine and is then immersed in a second aqueous bath containing a modifying agent selected from epoxy compounds, ethyleneimine compounds, urea, substituted urea compounds, thiourea, substituted thiourea compounds, alkylene carbonates, unsaturated carboxylic acids, derivatives of unsaturated carboxylic acids, unsaturated nitriles, unsaturated alcohols, esters of an unsaturated alcohol, sulfonic acid salts having a vinyl group, cyanic acid salts, nonionic surfactants of a poly(alkylene oxide) type, salts of sulfates of the nonionic surfactants and silane coupling agents having a vinyl group. The treatment may also be performed by a one step process in which wool is immersed in an aqueous bath containing the above phosphine compound and a modifying agent selected from the above.
摘要:
THE PRESENT INVENTION RELATES TO NOVEL PROCESSES BY WHICH SUBSTITUENT GROUPS AND CROSSLINKS CAN BE INTRODUCED INTO CELLULOSE AND OTHER POLYMERIC COMPOSITIONS CONTAINING REACTIVE HYDROXYL GROUPS. THE NOVEL PROCESSES OF THIS INVENTION AND THE NOVEL PRODUCT OF THIS INVENTION ARE BASED ON THE DISCOVERY THAT QUATERNARY AMMONIUM AND TERTIARY AMINO HYDROXIDE GROUPS DEVELOPED AS SUBSTITUENTS IN POLYMERIC COMPOSITIONS, CATALYZE THE EACTION OF ACTIVATED VINYL COMPOUNDS WITH THE HYDROXYL GROUPS OF THESE POLYMERS.
