A polymeric composition includes a resin including an ethylene-based polymer and a copolymer of ethylene and an alpha olefin comonomer. The resin has a High Mw Comonomer Content of 3.2 wt % or greater based on a total weight of the resin over the weight average molecular weight range of 10g/mol to 10g/mol as measured by Ethylene GPC. The polymeric composition has a Relevant Comonomer Content of 0.6 wt % or greater. The polymeric composition also includes at least one of (i) a polydimethylsiloxane having a weight average molecular weight of 550,000 g/mol to 650,000 g/mol as measured according to Component GPC and (ii) a polymeric ultraviolet light stabilizer comprising a hindered amine moiety and having a weight average molecular weight from 5,000 g/mol to 20,000 g/mol as measured according to Component GPC.

Polymeric compositions

A polymeric composition includes (i) a copolymer of ethylene and an alpha olefin comonomer, the copolymer having a density of 0.945 g/cc to 0.960 g/cc, (ii) an ethylene-based polymer, and (iii) polyethylene glycol. The combination of (i) and (ii) has a High Mw Comonomer Content of 3.2 wt % or greater based on a total weight of the combined (i) and (ii) over the weight average molecular weight range of 10g/mol to 10g/mol as measured by GPC, wherein 15 wt % or greater of the total weight of the polymeric composition is the combined (i) and (ii) having a molecular weight in the range of 10g/mol to 10g/mol as measured by GPC, wherein the polymeric composition has a Relevant Comonomer Content of 0.6 wt % or greater and wherein the polymeric composition has a density of 0.945 g/cc or greater as measured according to ASTM D792.

Enhanced aging and reduced shrinkback polymeric composition

A polymeric composition includes an ethylene-based polymer, one or more of an ionomer and an acid copolymer, a flame-retardant filler, and a maleic anhydride functionalized polyolefin. The polymeric composition has an MAH Product of 3 or greater.

Flame retardant polymeric compositions

A continuous process for producing a polyurea concentrate or powder. The process includes combing at least one amine and an isocayante in the presence of a liquid diluent or a base oil in a rotor stator mixer. The concentrate comprises a polyurea in a base oil wherein the concentration of from about 20 weight percent to about 50, or 40 or 35 or 30 weight percent of polyurea based on total weight of grease thickener. The powder has particle size of 2 to 400 microns. This concentrate or powder can then be formulated by grease manufacturers to the desired final properties without the need for handling of the isocyanate and amine raw materials.

Method of making a grease thickener and the thickener made by the method

An aqueous ionomer dispersion, and method of manufacturing thereof, comprising an ionomer composition and water, wherein the ionomer composition comprises: a) at least 20 wt. %, based on the total weight percent of the ionomer composition, of an ionomer; and b) up to 80 wt. %, based on the total weight percent of the ionomer composition, of a polyolefin.

Aqueous ionomeric dispersions, and methods thereof

A continuous process for producing a polyurea concentrate or powder. The process includes combing at least one amine and an isocyanate in the presence of a liquid diluent or a base oil in a rotor stator mixer. The concentrate comprises a polyurea in a base oil wherein the concentration of from about 20 weight percent to about 50, or 40 or 35 or 30 weight percent of polyurea based on total weight of grease thickener. The powder has particle size of 2 to 400 microns. This concentrate or powder can then be formulated by grease manufacturers to the desired final properties without the need for handling of the isocyanate and amine raw materials.
