ETHYLENIC RESIN COMPOSITION

摘要

PURPOSE: To provide an ethylenic resin composition for extrusion molding generating slight rough surface and fuming or scums in molding, suitably used for extrusion molding and obtainable of a molded material having high rigidity and high strength. CONSTITUTION: The objective ethylenic resin composition is composed of 30-60wt.% below-cited component (A) and 70-40wt.% component (B). (A) An ethylenic polymer having 50-1000g/10min MFR(melt flow rate) at 190 deg.C and <=2.2 of a ratio of complex viscosityη1 * at G1 *=1.94×10<4> Pa to complex viscosityη2 * at G2 *=1.94×10<5> Pa:η1 */η2 * in a curve of complex viscosity (η*) vs. complex modulus (G*) measured at 190 deg.C. (B) An ethylenic polymer having 1.0-5.0g/10min HLMFR(high load melt flow rate) at 190 deg.C and >=3.0 of a ratio of complex viscosityη1 * at G1 *=1.94×10<4> Pa to complex viscosityη2 * at G2 *=1.94×10<5> Pa:η1 */η2 *.
