Abstract:
1. A method for obtaining UHMWPE containing at least one component comprising: providing UHMWPE in the form of a powder; compacting the UHMWPE at a temperature below the melting temperature of the UHMWPE and at a pressure greater than atmospheric pressure, for a time, temperature, and pressure sufficient to form at least a first dense body comprising deformed porous powder particles formed from UHMWPE, wherein the deformed porous powder particles of the first dense body are not completely fused and comprise narrow channels throughout the first dense body, wherein the narrow channels are capable of supporting rapid and uniform liquid adsorption into the first dense body due to capillary forces in the narrow channels; providing at least a first component as a liquid; exposing at least a portion of the first dense body to the first component as a liquid, wherein the liquid is drawn into the first dense body by capillary forces in the narrow channels of the first dense body thereby forming a composition comprising UHMWPE and the at least first component.
