Title:
FILM COMPRISING ETHYLENE/C4-20 α-OLEFIN/NON-CONJUGATED POLYENE COPOLYMER
Document Type and Number:
Japanese Patent JP2014133785
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a film comprising an ethylene/C4-20 α-olefin/non-conjugated polyene copolymer which has advantages of flexibility and low permanent elongation, causes little necking, and has high resistance against tension and high restorability.SOLUTION: The film of the present invention is obtained from an ethylene/C4-20 α-olefin/non-conjugated polyene copolymer satisfying the following requisites (i), (ii), and (iii): (i) the molar ratio of constituent units [A] derived from ethylene with respect to constituent units [B] derived from α-olefins having carbon numbers of 4-20, namely [A]/[B], is in a range of 50/50-95/5; (ii) the ratio of constituent units [C] derived from non-conjugated polyenes is in a range of 0.1-5 mol% when a total of constituent units [A], [B], and [C] is defined as 100 mol%; and (iii) the Mooney viscosity at 100°C MLis in a range of 10-200.
