Provided is an irradiation-crosslinked ethylene propylene diene monomer (EPDM) composition containing: EPDM 30 to 80 phr (parts per hundred resin) free of a crosslinking agent, a polyolefin (PO) resin 10 to 50 phr, a silicone rubber 5 to 40 phr, a flame retardant 20 to 30 phr, a crosslinking accelerator 5 to 10 phr, a crosslinking assistant 1 to 5 phr, an antioxidant 5 to 15 phr, and a lubricant 0.25 to 5 phr. Provided is a cable produced by: providing the irradiation-crosslinked EPDM composition; first kneading the composition using a kneader; second kneading the first kneaded composition using a roll mill; extruding the second kneaded composition using an extruder, and then cutting the extruded composition to produce pellets as a raw material for the cable; forming a cable of a predetermined length by extruding the pellets using an extruder; and irradiation-crosslinking the formed cable using an electron beam accelerator.

The present invention discloses a method for preparing high-melt-strength polylactide resin by two-step reaction, which comprises the following steps: mixing polylactide resin and GMA to obtain a premix; mixing multifunctional reactive monomer, a peroxide initiator and organic solvent to obtain a monomer mixture; and adding the premix and the monomer mixture into a screw extruder in sections, after melting, blending, extruding, cooling, pelletizing and drying to obtain a high melt strength polylactide resin. The method of the present invention has a simple production process, can be adapted to large-scale industrial production, the graft modification reaction is rapid and controllable, and the obtained product is safe without residue and high in purity. The high-melt-strength polylactide resin has a low melt flow index, high complex viscosity and storage modulus, and is a green polymer material with wide application prospects.
