POLYOLEFIN RESIN COMPOSITION HAVING CAPACITY OF CHANGING WAVELENGTH, MASTERBATCH FOR THE SAME AND AGRICULTURAL FILM MADE FROM THE SAME

摘要

PROBLEM TO BE SOLVED: To obtain a polyolefin resin composition which does not deteriorate in performances even when exposed to sunshine for a long term and has sufficient film strength by mixing a specified ethylene (co)polymer with a specified compound and a hindered amine compound. SOLUTION: This composition comprises 100 pts.wt. resin comprising 100-20wt.% ethylene homopolymer or ethylene/3-20 C -olefin copolymer satisfying the following four requirements: the density is 0.86-0.96g/cm3 , the MFR is 0.01-100g/10min, the molecular weight distribution (Mw/Mn) is 1.5-5.0, and the compositional distribution parameter Cb is 2.00 or below and 0-80wt.% other olefin (co)polymers, 0.05-18 pts.wt. compound represented by formula II [wherein R1 to R4 , which are independent of each other, are divalent hydrocarbon groups or the like; X1 to X4 , which are independent of each other, are hydrogen atoms, acryloyloxy groups or methacryloyloxy groups] or polymer thereof and 0.05-2 pts.wt. hindered amine compound.
