摘要: Polymers of anionically polymerized monomers such as conjugated dienes, vinyl substituted aromatics, olefinic type compounds, and heterocyclic nitrogen containing compounds, are produced and end capped with a polyisocyanate or polyisothiocyanate. Such end capped polymers are then reacted with compounds containing an amide such as lactam to give an imide type end group. The imide type terminated polymer is hydrolyzed to form a stable amine terminated polymer which may be utilized, as a composition of matter or stored for a short period of time to an extended period of time and reacted with other various polymers and monomers, or various combinations of monomers to form various block or graft polymers. That is the amine polymer may be subsequently reacted with any amine reactive compound such as with a polyisocyanate or polyisothiocyanate and a lactam in the presence of a known anionic lactam polymerization catalysts to give a blocked nylon copolymer. Similarly, other block or graft coplymers may be obtained by reacting amine reactive compounds such as various monomers or polymers with the terminated amine polymer and examples of amine reactive polymers include polyepoxy, polyurea-aldehyde, polyphenol-aldehyde, polyamide, polyurea-urethane, polyurethane, polyimide, polyurea and similar polymer segments. Of course, identical or similar polymer forming reagents such as monomers as well as identical or similar prepolymers may also be used.

摘要: Polymers of anionically polymerized monomers such as mono-olefins, conjugated dienes, vinyl substituted aromatics, vinyl substituted pyridine, vinyl substituted quinolines, various aldehydes, various epoxides, various oxetanes, various oxygen-containing compounds, and the like are produced and end capped with a polyisocyanate or polyisothiocyanate having the formula R--N.dbd.C.dbd.X).sub.n wherein R is a hydrocarbon, n is 2 or 3, and X is oxygen or sulfur. Such end capped polymers, of course, contain one reacted or connected isocyanate or isothiocyanate group and at least one free isocyanate or isothiocyanate end group, which free end group(s) reacts with an amide to give an imide end group. The imide terminated polymer is then hydrolyzed to form a stable amine terminated polymer. The reaction of the amide compound with the isocyanate(s) or isothiocyanate(s), followed by hydrolysis, results in the replacement of the free isocyanate or isothiocyanate end group(s) with an amine group(s). Thus, the amine terminated polymer contains the polymer connected to an isocyanate or isothiocyanate group (now an amide group or a thioamide group), which in turn is attached to the hydrocarbon portion, that is, the "R" portion of the polyisocyanate, which in turn is connected to the formed amine group. The amine terminated polymers may be stored extended periods of time and then reacted with various polymers, prepolymers, monomers, or various combinations thereof to form various block or graft copolymers. That is, the amine terminated polymer may be subsequently reacted with any amine reactive compound such as diepoxy monomers or an epoxy prepolymer in the presence of known epoxy catalysts to give a blocked epoxy copolymer. Similarly, the amine terminated polymer may be reacted with urea prepolymers or urea-forming monomers to yield a block urea copolymer. Reaction of the amine terminated polymer with urethane polymers, urethane prepolymers, or urethane-forming momomers will yield a urethane block copolymer. Reaction of the amine terminated polymer with urethane-urea prepolymers of urethane-urea forming monomers will yield a urethane-urea block copolymer. Similarly, various dianhydride and diamine monomers may be utilized to form an imide block copolymer.
