This invention relates to a novel polyether polyol blend having an overall hydroxyl number of 56 mg KOH/g to 140 mg KOH/g, an overall functionality of greater than 2, and an overall content of copolymerized oxyethylene of 20% to 40% by weight. These novel polyether polyol blends may also be in-situ formed novel polyether polyol blends. A process for preparing these novel polyether polyol blends is also disclosed. These novel polyether polyol blends are suitable for preparing viscoelastic flexible polyurethane foams, and in a process for preparing viscoelastic foams.

Methods of forming a gel and related methods of treating subjects with such gels are described. The method may include preparing a composition by combining a macromer comprising a first polyethylene glycol (PEG)-based polymer, a poly(ethylenimine)-based polymer, or a poly(1,2-glycerol) carbonate-based polymer, the macromer including at least one first functional moiety, a crosslinking agent comprising a second PEG-based polymer that includes at least one second functional moiety, and a photoinitiator, and activating the photoinitiator via a light source to form the gel.
