Abstract
Disclosed is a method for the manufacture of coextruded plastic sheeting from normally incompatible, i.e. difficultly bondable, polymers and the composite sheeting produced thereby. A composite plastic sheeting of a solid hydrocarbon polymer and an ABS polymer normally incompatible therewith is formed by coextruding the hydrocarbon and incompatible ABS polymer with an intermediate layer interposed therebetween of an ABS polymer having a bonding factor and a melt viscosity between each of the hydrocarbon and incompatible ABS polymers which renders the intermediate layer ABS polymer strongly adherable to each adjoining polymer.
