Abstract

A rigid chain entanglement crosslinked polymer made by dispersing at lease one monomer and at least one initiator in an immiscible liquid medium to form a liquid dispersion; and decomposing the initiator in the fluid dispersion to activate polymerization and thereby produce a chain entanglement crosslinked polymer; and the polymer that can be utilized as proppants, as ball bearings, as lubriglide monolayers, and for drilling mud applications
