Abstract:
To provide a resin composition comprising a cyclic polyolefin and an ethylene polymer, having excellent impact resistance and having high transparency maintained.
A resin composition comprising from 5 to 95 parts by weight of a cyclic polyolefin (A) and from 5 to 95 parts by weight of an ethylene polymer (B) which satisfies the following requirements (a) to (d) (the total amount of (A) and (B) is 100 parts by weight): (a) the density is from 930 to 960 kg/m3; (b) MFR is from 0.1 to 15.0 g/10 min; (c) in molecular weight measurement by gel permeation chromatography, two peaks are observed, and the ratio (Mw/Mn) of the weight average molecular weight (Mw) to the number average molecular weight (Mn) is within a range of from 3.0 to 7.0; and (d) a fraction having Mn of at least 100,000 as obtained by molecular weight fractionation, has at least 0.15 long-chain branches per 1,000 carbon atoms of the main chain.
