Patent number: 5464585Abstract: The invention provides an improved process for molding articles having a bulk material and an auxiliary material, such as an additive, a comonomer, or a catalyst, present in the bulk material as a fixed concentration strip or in a concentration gradient in the direction from the surface to the interior. The invention is especially useful for concentrating surface-enhancing auxiliary materials at the surface of an article without wasting the auxiliary material in the interior of the article where it provides minimal value. This invention is also applicable to concentrating an interior-enhancing auxiliary material in the interior of the article without degrading surface sensitive properties. The method for manufacturing an as-molded article having a bulk material and an auxiliary material provided therein generally comprises injecting a moldable bulk material composition into a mold with an essentially laminar flow profile such that the earlier injected material will reside at the surface of the mold (i.e.Type: GrantFiled: January 3, 1994Date of Patent: November 7, 1995Assignee: Metton America, Inc.Inventor: Denise R.

Patent number: H1807Abstract: The process of metal plating an object formed out of a cyclic olefin polymer is improved by first immersing the object in an organic solvent, such as an aromatic hydrocarbon or a halogenated aliphatic hydrocarbon, that serves to swell the object at its surface, for example sufficiently to increase its weight by about 0.1 to 70%. In this way objects molded out of, for example, poly(dicyclopentadiene) can be pre-etched by being immersed in xylene for 5 minutes at room temperature, and then plated by the electroless deposition of nickel on the surface of the etched part. The pre-etching facilitates adhesion of the plating metal to the surface.Type: GrantFiled: July 10, 1998Date of Patent: October 5, 1999Assignee: Metton America, Inc.Inventor: Harry Sutton Anderson, II
