An array of dies having a closed configuration is used in a method and apparatus for making a closed composite article that comprises multilayered materials. In the method and apparatus, at least two extruders are used to extrude at least two material streams through the die array to provide an extrudate comprised of alternate layers of material from the at least two material streams. The compositions in the two material streams can be the same or different.

Closed die array for multi-layered articles

An improved method of bonding at least two cured or uncured elastomeric layers is disclosed. The method comprising placing an uncured elastomeric component ( ) between the two elastomeric layers, and curing the elastomeric component to bond the elastomeric layers together. The improvement is characterized by forming the uncured elastomeric component ( ) by preparing two non-productive elastomer compounds ( ), wherein each non-productive compound ( or ) is prepared with a co-reacting agent of a co-reacting cure package not added to the other non-productive compound ( or ), and layering the non-productive elastomer compounds ( ) in alternating layers with a thickness relative to the diffusion rate of the co-reacting agents in each non-productive elastomeric layer ( ) to effect diffusion of the co-reacting cure agents through the adjacent layers.

Bonding elastomeric articles

The present invention relates to a rubber article having a surface construction designed for abrasion resistance wherein the surface comprises a series of rubber layers parallel to each other and in a density of from at least 200 layers per 25.4 millimeters as measured along the surface area of the article and in a direction perpendicular to each layer.

Rubber article having a surface design for high abrasion resistance

A method of reducing the monomer content of a polymer or polymerization media comprising subjecting the polymer containing the monomer to sufficient irradiation with a high energy radiation to polymerize said monomer, said radiation preferably occurring in presence of chemical agent that accelerate the rate of consumption of the undesirable monomer, i.e. the monomer considered hazardous and/or protects the polymer from radiation degradation.
