Abstract:
1. A method to synthesize an ultra-high molecular weight polymer, the method comprising: combining an ethylene monomer, an additive, and a catalyst suitable for polymerization of monomers with a solvent in a mixture comprising a liquid phase, wherein the additive is a colloidal stabilizer capable of a crystal forming interaction with a nascent polymer comprising the monomer, the colloidal stabilizer comprising a solvophilic portion soluble in the solvent and a crystalphilic portion capable of interacting with the polymer to form a co-crystal comprising the polymer and the crystalphilic portion; the additive being chemically inert with respect to the catalyst, the monomers, the nascent polymer and the ultra-high molecular weight polymer; and the combining is performed in the liquid phase for a time and under conditions to allow synthesis of the nascent polymer, and co-crystallization of the nascent polymer with the additive thereby resulting in a colloidal suspension of the ultra-high molecular weight polymer comprising detectable crystals.
