A room-temperature vulanizable (RTV) polymeric composition comprising organosiloxane or polyurethane units having at least one terminal methyl isopropyl ketoximino or methyl propyl ketoximino moiety, as well as methods of making the same.

Room temperature vulcanizable polymers

An O-substituted hydroxylamine having the following general formula:R&#x2014;CHX&#x2014;O&#x2014;NHwherein X is hydrogen or an alkyl; and Ris an unsubstituted or substituted phenyl, thienyl, furanyl, pyrrolyl or &#x2014;CR&#x2550;CRR; wherein R, Rand Rare hydrogen, halogen or alkyl. The O-substituted hydroxylamine exhibits at least one property selected from the group consisting of: essentially free of hydroxylamine; essentially free of any solvent; a water content of between about 0% to 90% by weight; and a high strength (as measured by mole of the O-substituted hydroxylamine per gram of sample) of between about 0.5 to 3.3-fold as much as a 40% O-substituted hydroxylamine salt solution, by weight. The O-substituted hydroxylamine further comprising at least one additional property selected from the group consisting of: a purity of between about 98% to 100%, based on gas chromatographic area; and a purity drop of less than about 1.2% after 78 days at 40&#xb0; C. when the O-substituted hydroxylamine has a concentration of about 85% in water, based on gas chromatographic area. The O-substituted hydroxylamine is at least one isomer selected from the group consisting of cis, trans and a mixture thereof. The O-substituted hydroxylamine may also be reacidified to an O-substituted hydroxylamine salt free of hydroxylamine.
