Abstract
A process includes combining a copolymer and mono- or di-valent metal ions to form a mixture, wherein the copolymer has from about 70 to about 98 wt % of an alpha-olefin moiety and about 2 to about 30 wt % of a (meth)acrylate moiety; reactively extruding the mixture to form a neutralized copolymer having a melt flow index of from about 5 to about 1500 g/10 min, wherein about 2 to about 50 wt % of the (meth)acrylate moiety is neutralized to form a mono- or di-valent metal salt present in an amount of from about 0.2 to about 20% based on the total (meth)acrylic acid content of the copolymer; and grinding the neutralized copolymer to form the powder having a Dv50 particle size of from about 10 to about 600 μm as determined using ASTM D5861, wherein the process is free of utilizing a liquid and/or a slurry.
