POLYCARBONATE-BASED RESIN COMPOSITION FOR EXTRUSION USING SIZING DIE AND MOLDED ARTICLE |
摘要 |
<p>A polycarbonate-based resin composition for extrusion molding using a sizing die, comprising as a main component, a polycarbonate having a viscosity-average molecular weight of 17000 to 27000 and containing main repeating units represented by the following formula (A): <CHEM> wherein an amount of proton (Pa) and an amount of proton (Pb) per 1 g of the polycarbonate which are calculated from respective integral values of a signal (a) detected at delta = 7.96 to 8.02 ppm and a signal (b) detected at delta = 8.11 to 8.17 ppm in <1>H-NMR spectra thereof as measured in a deuterated chloroform solvent, satisfy the following formula (1) : <DF NUM="(1)">4 < ä(Pa) + (Pb)ü < 26 </DF> wherein a unit of each of (Pa) and (Pb) is mu mol/g; as well as a molded product produced by extrusion-molding the resin composition using a sizing die. The above polycarbonate resin composition exhibits good mechanical properties and a good moldability, and is suitable for extrusion molding using a sizing die.</p> |
