1. An aqueous suspension of a water soluble polymer that is anionic or non-ionic comprising a blend of water with at least about 32 wt % chloride salt with a counter ion A+a with 2≤a, from about 1 wt % to about 10 wt % polyethylene glycol, and from about 10 wt % to about 50 wt % of the water soluble polymer that is not a polyether, wherein the aqueous suspension has chlorides in a sufficient amount to inhibit hydration of the water soluble polymer and the polyethylene glycol, and wherein the water soluble polymer and the polyethylene glycol are not hydrated and are suspended as a blend in the aqueous suspension.
