Abstract
The invention relates to a method for welding a polyamide plastic and a poly(meth)acrylate—particularly a polymethyl methacrylate—plastic using a primer, said primer containing at least one copolymer synthesised from at least one styrene or styrene derivative and at least one maleic anhydride or maleic anhydride derivative. The invention also relates to correspondingly welded products.
Claims18
A method for welding polyamide plastics and poly(meth)acrylate plastics, comprising:
- providing a polyamide plastic substrate having a surface defining a joining zone on a portion of that surface,
- providing a poly(meth)acrylate plastic substrate having a surface defining a joining zone on a portion of that surface,
- applying a primer onto the joining zone surface of at least one of the polyamide plastic substrate and the poly(meth)acrylate plastic substrate,
- positioning the polyamide plastic substrate joining zone adjacent the poly(meth)acrylate substrate joining zone so that the primer is disposed between the joining zones, and
- welding the polyamide plastic substrate joining zone to the poly(meth)acrylate substrate joining zone,
- wherein the primer contains at least one copolymer synthesized from at least one styrene or styrene derivative and at least one maleic anhydride or maleic anhydride derivative.
