FIBER-REINFORCED POLYMER COMPOSITION DERIVED FROM ORGANISM AND PROCESS FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a process for producing a fiber-reinforced polymer composition derived from an organism that has a short fiber of a thermotropic liquid-crystalline polyester uniformly dispersed in the form of a single fiber into a polymer derived from an organism and is producing a molded article excellent in dynamic characteristics, durability, heat resistance and the like smoothly with good workability and good progression of the production without the occurrence of clogging or the like in a heating and kneading apparatus. SOLUTION: The fiber-reinforced polymer composition derived from an organism is produced by blending and melt-kneading into a polymer derived from an organism a bundle of short fibers of a thermotropic liquid-crystalline polyester wherein the bundle of short fibers is constituted of short fibers temporarily bonded to each other through thermal fusion bonding with adhesive strength such as to separate the short fibers into each single fiber by heat and/or shearing force upon kneading.
