MULTILAYER FILM Russian patent published in 2010 - IPC B32B27/34 B32B27/08 C09J133/06 C09J133/14 

FIELD: chemistry.

SUBSTANCE: invention can be used for external and internal decoration of automobiles when joining layers made from polyamide moulding composition and a component made from acrylonitrile butadiene styrene (ABS) moulding composition. The adhesion promoter of the said compound contains from 2 to 100 wt % copolymer, containing from 70 to 99.9 wt % monomer units which are derivatives of vinyl compounds selected from a group comprising acrylic acid derivatives, methacrylic acid derivatives and derivatives of vinyl aromatic compounds, and from 0.1 to 30 wt % monomer units with functional groups selected from a group comprising a group of carboxylic acid anhydride, an epoxy group and an oxazoline group. The multilayer film contains at least one layer made from polyamide moulding composition and at least one layer made from an adhesion promoter of the said composition and made through co-extrusion or layering. The combined component consists of a component made from acrylonitrile butadiene styrene moulding composition and a multilayer film and is made by pressure moulding with packing the multilayer film into a press mould, co-extrusion, pressing, layering, injecting or foaming the adhesion promoter between the multilayer film and a base.

EFFECT: reliable joining of a polyamide layer with a component made from acrylonitrile butadiene styrene moulding composition.
