| titleOfInvention | Polybutylene terephthalate pellets, compound products thereof, molded articles thereof and methods for their preparation |
| abstract | Provided is a PBT pellet for producing a molded article excellent in color tone, hydrolysis resistance, transparency, molding stability and reduced foreign matter. In a pellet containing titanium and the amount thereof is 90 wt ppm or less in terms of a titanium atom and the terminal methoxycarbonyl group concentration is 0.5 μeq / g or less, the pellet has an average intrinsic viscosity of 0.90 to 2.00 It is dL / g, and the difference of the intrinsic viscosity of a pellet center part and a surface layer part is 0.10 dL / g or less. In a preferred form, the terminal carboxyl group concentration of the polybutylene terephthalate is 10-25 µeq / g, the terminal vinyl group concentration is 0.5-10 µeq / g, and the solution haze is 5% or less. However, the solution haze is taken as the value of turbidity of the solution which melt | dissolved 2.7 g of polybutylene terephthalates in 20 mL of phenol / tetrachloroethane liquid mixture (weight ratio 3/2). n n Polybutylene terephthalate pellet, terminal carboxyl group, solution haze, intrinsic viscosity difference, terminal methoxycarbonyl group, terminal vinyl group, titanium, molded article, color tone |
