Abstract
An adhesive resin composition, including from 60 to 95 parts by mass of an ethylenic polymer (A) including a modified ethylenic polymer (a-2) obtained by modifying at least one polymer (a-1) selected from the group consisting of an ethylene homopolymer and a copolymer of ethylene and at least one α-olefin selected from α-olefins having from 3 to 20 carbon atoms, with an unsaturated carboxylic acid and/or a derivative thereof, and from 5 to 40 parts by mass of a butene-based polymer (B) having 80 mol % or more of a structural unit derived from 1-butene, provided that the total content of the polymer (A) and the polymer (B) is 100 parts by mass, wherein the MER (190° C. and a load of 2.16 kg) is from 1 to 20 g/10 minutes.
Claims7
An adhesive resin composition, comprising:
- from 60 to 95 parts by mass of an ethylenic polymer (A) comprising a modified ethylenic polymer (a-2) obtained by modifying at least one polymer (a-1) selected from the group consisting of an ethylene homopolymer and a copolymer of ethylene and at least one α-olefin selected from α-olefins having from 3 to 20 carbon atoms, with an unsaturated carboxylic acid and/or a derivative thereof;
- and
- from 5 to 40 parts by mass of a butene-based polymer (B) having 80 mol % or more of a structural unit derived from 1-butene, provided that the total content of the polymer (A) and the polymer (B) is 100 parts by mass,
- wherein the adhesive resin composition has a melt flow rate as measured at 190° C. and under a load of 2.16 kg in accordance with ASTM D1238 is in a range of from 1 to 20 g/10 minutes,
- wherein the butene-based polymer (B) is a copolymer of 1-butene and α-olefin(s) selected from the group consisting of ethylene and propylene.
