Abstract
Polybutylene terephthalate containing a titanium catalyst in an amount of not more than 150 ppm, calculated as a titanium atom and having an end methoxycarbonyl group concentration of not more than 0.5 μeq/g, an active titanium content (α) in the titanium catalyst, defined by the following formula (I), being not less than 0.8, α =X/[M] (I) wherein [M] is a titanium atom concentration (ppm) in polybutylene terephthalate; and X is an activation parameter defined by the specific formula. The above PBT has excellent color tone, hydrolytic resistance, heat stability, transparency and moldability as well as a less content of extraneous materials, and is suitably applicable to films, monofilaments, fibers, electric and electronic parts, automobile parts, etc.
