CARBON FIBER BUNDLE, PROCESS FOR PRODUCING THE SAME, AND THERMOPLASTIC RESIN COMPOSITION AND MOLDED ARTICLE THEREOF

WIPO Patent Application WO/2005/012604

A2

A carbon fiber bundle which can have satisfactory interfacial adhesion to polyolefin resins, especially polypropylene resins. The carbon fiber bundle comprises two or more fibers and has been sized with a sizing agent comprising either a polymer which has a main chain made up of carbon-carbon bonds, has an acid group in at least part of the side chains or at at least part of the ends of the main chain, and has an acid value as measured in accordance with ASTM D 1386 of 23 to 120 mg-KOH/g or a polymer which has a main chain made up of carbon-carbon bonds and has at least either of epoxy and ester groups in at least part of the side chains or at at least part of the ends of the main chain.
