Abstract

Disclosed is a polyolefin-based adhesive. The adhesive comprises a maleated polyolefin. The maleated polyolefin is let-down in a linear low density polyethylene (LLDPE). The let-down LLDPE is selected from those which have a melt index MI2 within the range of 0.1 dg/min to 5 dg/min, preferably from 1 dg/min to 3 dg/min, and comprises a TREF soluble fraction having an intrinsic viscosity less than 0.9 dl/g. The adhesive composition can be used in multilayer polyolefin films and multilayer pipes.
