A method for producing a trim component for vehicle interior is disclosed. The method may produce multilayer molded bodies (e.g. interior compartments/fittings for vehicles) in which a reverse side of a leather material is backed with a plastic by injection molding. In order to prevent the leather material from being damaged by the injection pressures and/or temperatures during the in-mold injection molding process, the method provides for introducing untreated leather material into the injection mold.

Described herein are strength characteristics and biodegradation of articles produced using one or more petrochemical-based polymers and one or more carbohydrate-based polymers. A compatibilizer can optionally be included in the article. In some cases, the article can include a film or bag.

A method of making a plastic tank suitable for containing water comprises forming a tank base which is partially or fully lined with a plastic layer that is different in character or color from the plastic material of the substrate of the tank base. The tank is alternatively formed by injection molding substrate material around the core of a mold which is partially or fully covered by the liner material, and by injecting liner material into the mold to bond it to the tank base substrate in conjunction with retracting part or all of the core, to provide space in the mold for the liner material.

Layered polymer materials include a first layer including a first cyclic olefin polymer or a first cyclic olefin copolymer, a third layer including a second cyclic olefin polymer or a second cyclic olefin copolymer, and a second layer including an amphiphilic polymer having a hydrophilic component with a Hansen Solubility Parameter distance of 8 MPa.sup.1/2 or greater from oxygen gas, while at the same time having a hydrophobic component with a Hansen Solubility Parameter distance of 8 MPa.sup.1/2 or less from COC or COP. The second layer can be in contact with and be between the first layer and the third layer. The layered polymer material can be used to construct the body of a vial or a syringe. Methods of making the layered polymer material and kits containing the layered polymer material or containers having a body constructed from the layered polymer material are also described.

The present invention relates to a method for producing a plastic compound having improved properties from a formulation containing at least two thermoplastic components in a multi-shaft screw machine having screw shafts rotating in the same direction, in parallel and at the same speed, wherein the plastic compound (i) does not comprise an additive which is flowable at 23 C. or (ii) comprises precisely one additive which is flowable at 23 C., or (iii) comprises at least two additives which are flowable at 23 C. The present invention relates in particular to the production of a plastic compound from a formulation containing at least two thermoplastic components, at least one of which is a polycarbonate. More particularly, the screw machine is a twin-screw extruder having screw shafts rotating in the same direction, in parallel and at the same speed.
