Extrusion of polyolefin onto paper at decreased temperatures |
摘要 |
By coating a paper substrate first with a polyalkyleneimine and then with a polymer containing groups which react chemically with the imino groups of the polyalkyleneimine, a polyolefin can be extruded onto the substrate with good adhesion at temperatures lower than the temperature that would be required to obtain the same degree of adhesion if the polymer containing the reactive groups were not present.
