Abstract
A coagent masterbatch comprising a semi-crystalline polyolefin carrier resin and an alkenyl-functional coagent. A peroxide curable formulation comprising the coagent masterbatch and a polyolefin compound. A method of making the masterbatch and formulation; a peroxide-cured polyolefin product prepared therefrom; a manufactured article comprising or made from the masterbatch, formulation, or product; and a method of using the manufactured article.
Claims14
A coagent masterbatch comprising (A) a semi-crystalline polyolefin carrier resin and (B) an alkylene-functional coagent disposed in the (A) semi-crystalline polyolefin carrier resin, and (C) an organic peroxide disposed on and/or in the (A) semi-crystalline polyolefin carrier resin;
- wherein the (A) semi-crystalline polyolefin carrier resin has a crystallinity of from 55.0 to less than 100 weight percent (wt %) as measured by Crystallinity Test Method using differential scanning calorimetry (DSC);
- wherein the (A) semi-crystalline polyolefin carrier resin is a semi-crystalline polyethylene or a semi-crystalline poly(ethylene-co-alpha-olefin) copolymer;
- wherein (A) has a density of greater than 0.935 gram per cubic centimeter (g/cm3);
- wherein (A) is 70.0 to 99.9 weight percent (wt %) and (B) is from 30.0 to 0.1 wt % of the combined weight of constituents (A) and (B);
- and wherein (C) is from 0.01 to 4.5 wt % of the total weight of the coagent masterbatch.
