BRANCHED POLYARYLENE SULFIDE RESIN, METHOD FOR MANUFACTURING SAME AND USE AS POLYMER MODIFIER |
| 摘要 |
Disclosed is a branched polyarylene sulfide resin including an —S— substituent group with a cleaved disulfide compound which has a melt viscosity as measured at a halogen content of 4,000 ppm or less, a temperature of 330° C. and a shear rate of 2 sec−1 of 1.0×104 to 50.0×104 Pa·s and a melt viscoelasticity tan δ as measured at a temperature of 310° C. and an angular velocity of 1 rad/sec of 0.1 to 0.6. |
