  • Publication number: 20100298500
    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.

  • Publication number: 20100174036
    Abstract: Disclosed is a method for preparing polyolefin-based adhesives. In the method, a maleated polyolefin is blended, in sequence, with a polyolefin elastomer and then with a linear low density polyethylene. The polyolefin-based adhesive made according to the method of the invention shows improved clarity and adhesion in multilayer polyolefin films.

  • Publication number: 20100098958
    Abstract: A laminate and a process for making it are disclosed. The laminate comprises a metal substrate and a polymer layer that adheres to at least one plasma-treated surface of the metal substrate. The polymer layer comprises a blend of a first polyolefin and a grafted polyolefin. The laminate can be prepared by plasma-treating at least one surface of a metal substrate and extruding onto the plasma-treated surface a polymer layer comprising a blend of a first polyolefin and a grafted polyolefin.
