Document Type and Number:
WIPO Patent Application WO/2007/032081
Kind Code:
A1
Abstract:
The comonomer quantity and thermal stability of polyoxymethylene resin copolymer are restricted and further the method of feeding polyoxymethylene resin and carbon in extrusion operation is delved deeper into to thereby enable production of a master batch excelling in thermal stability. Moreover, the composition loaded with the master batch retains mechanical properties (elastic modulus, impact resistance and vibration fatigue characteristic), chemical resistance and moldability, and has conducting capability.
