The present disclosure is drawn to polymeric amine synergist compositions. The polymeric amine synergist composition can include a polymeric amine synergist including an aminobenzene modified with a polyether chain connecting to the aminobenzene through an ether linkage. The polymeric amine synergist can be present in a reaction product mixture with either i) an aminophenol, or ii) a carbonate base.

A polymeric amine synergist is disclosed herein. An example of the polymeric amine synergist includes an aniline moiety, a polyethylene glycol chain, and an ether linkage attaching one end of the polyethylene glycol chain to the aniline moiety. The polymeric amine synergist may be included in a photo curable ink composition.

The disclosure provides products and methods of treating diseases and disorders involving microbial pathogens, such as intestinal microbial pathogens, e.g., Pseudomonas aeruginosa, by administering an effective amount of a phosphorylated polyethylene glycol compound of defined structural organization. Those diseases and disorders characterized by an epithelium attacked by a microbial pathogen are contemplated, including gastrointestinal infections and inflammation, e.g., treatment of intestinal or esophageal anastomosis or treatment or suppression of anastomotic leakage.

The present disclosure is drawn to a polymeric photo active agent which includes diphenyl(2,4,6-trimethylbenzoyl)phosphine oxide modified with a polyether having from 2 to 200 ether groups.
