PURPOSE:The titled composition having improved high-temperature adhesiveness, comprising a linear low-density polyethylene derived from 5-10C alpha-olefin and a modified linear low-density polyethylene derived from 3-4C alpha-olefin. CONSTITUTION:(A) A linear low-density polyethylene which contains 0.1-10mol% unit derived from 5-10C alpha-olefin, has 0.1-10g/10min melt index and 0.91-0.94g/cm<3> density and/or a modified material thereof with an alpha,beta-unsaturated carboxylic acid is blended with (B) a modified material obtained by grafting 0.1X10<-4>-4.5X10<-4>mol alpha,beta-unsaturated carboxylic acid onto 1g linear low-density polyethylene which contains 0.1-10mol% unit derived from 3-4C alpha-olefin (preferably butene-1), has 0.1-20g/10min melt index and 0.9-0.95g/cm<3> density in the weight ratio of the component A:B=60:40-99:1. |
