摘要:
Disclosed are a reinforcing fiber bundle composed of a carbon fiber bundle treated with an emulsion; a carbon fiber reinforced thermoplastic resin molded body using the same; and a method for producing a reinforcing fiber bundle; wherein the emulsion contains a modified polyolefin (A1) comprising at least a metal carboxylate bonded to the polymer chain, and 0.1 to 5,000 moles of an amine compound (B) represented by the following general formula (1), per one mole of the carboxylate group in the modified polyolefin (A1);
R-NH 2 (1)
wherein the formula (1), R is a hydrogen atom or a hydrocarbon group having 1 to 10 carbon atoms.

摘要:
The invention provides a process for producing an unsaturated hydrocarbon by dehydrogenating a hydrocarbon into a corresponding unsaturated hydrocarbon with use of a nontoxic catalyst having a long catalytic life. The process for producing unsaturated hydrocarbons includes a step of dehydrogenating a hydrocarbon into a corresponding unsaturated hydrocarbon by contacting the hydrocarbon with a catalyst A that is obtained by supporting zinc and a Group VIIIA metal on a silicate obtained by removing at least part of the boron atoms from a borosilicate.
