Abstract: A two-part curable composition is provided that includes a first part that includes an oxamido-containing compound and a second part that includes an epoxy resin. The oxamido-containing compound includes at least one first segment derived from a first polyamine and at least one second segment derived from a second polyamine that is different than the first polyamine. The oxamido-containing compound has at least two amino (—NH2) groups that can react with the epoxy resin in the second part of the curable composition. Each part of the curable composition is flowable, often at room temperature or slightly above room temperature, and can be mixed to form a cured composition having structural bonding performance.

Abstract: The present invention relates to new carbonyl 3R, 4R-ethyl-[(1-methyl-1H-imidzaol-5-yl)methyl]-2-pyrrolidinone derivatives carrying a carboxyester-type lipophilic moiety on the pyrrolidinone nitrogenand are valuable antiglaucoma agents and targeted for use in the treatment of so-called dry eye.More particularly, the present invention concerns new N-substituted carbonyl-3R, 4R-ethyl-[(1-methyl-1H-imidazol-5-7)methyl]-2-pyrrolidinone derivatives of the formula (I): ##STR1## wherein R is selected from the group consisting of ##STR2## wherein R.sup.1 is a halo radical, e.g. a chloro radical, or a lower alkyl radical, e.g. a methyl or ethyl radical, with the proviso that when m is 1, R.sup.1 is not methyl or t-butyl, m is an integer of 1 or 2, n is 0 or an integer of 1 or 2 and X is O or S, and pharmaceutically-acceptable acid addition salts thereof.
