Abstract
The invention relates to a novel halogen-free and acid-free, readily soluble adhesion promoter for polyolefins, said promoter containing (meth)acrylate-grafted, amorphous polyolefins.
Claims15
An adhesion promoter for comprising
- a polymer type A, a polyolefin or a polyolefin mixture,
- a polymer type B, a (meth)acrylate homo- or/and copolymer comprising standard methacrylates and/or standard acrylates, and
- a polymer type AB, a graft copolymer made of polymer type A and polymer type B,
- wherein the adhesion promoter is in the form of a melt, a dispersion, or a solution and is halogen-free and acid-free.
