Abstract

PURPOSE: To provide a resin composition for thermoforming giving a high-strength molten body during molding and a molded article with excellent secondary processability, by blending a resin composition comprising polypropylene and polyethylene with an amorphorus ethylene-propylene copolymer.
CONSTITUTION: 100pts.wt. resin composition comprising 65W97wt% polypropylene and 35W3wt% polyethylene is blended with 1W10pts.wt. amorphous ethylene-propylene compolymer. Polypropylene to be used has a molt index of 5g/10min or less and a density of 0.89W0.93g/cm3. Use of medium-density or low-density polyethylene results in deterioration in punching quality, regidity and heat resistance of the resin composition and a thermoformed resin sheet so that high-density polyethylene is preferable. As an amorphous ethylene-propylene copolymer, the one having a Mooney viscosity of 40W100ML1+4(100°C) and a propylene content of 10W70wt% is used.
