Patent number: 8212078Abstract: This invention provides aromatic diimines where the diimines have imino groups with at least two carbon atoms, and either are in the form of one benzene ring having two imino groups on the ring, which imino groups are meta or para relative to each other, and in which each position ortho to an imino group bears a hydrocarbyl group, or are in the form of two benzene rings connected by an alkylene bridge and having one imino group on each ring, and in which each position ortho to an imino group bears a hydrocarbyl group.Type: GrantFiled: December 30, 2005Date of Patent: July 3, 2012Assignee: Albemarle CorporationInventors: John Y. Lee, Paul L. Wiggins, Judit Orgad, Mahmood Sabahi, Vernon O. Brandt, David W. Owens

Patent number: 8080626Abstract: This invention provides chain extender compositions. These compositions comprise (i) an aromatic primary diamine, and (ii) a component selected from the group consisting of: (a) an aliphatic secondary diamine; (b) an aliphatic primary diamine; (c) an aliphatic secondary diamine and an aliphatic primary diamine; (d) a diimine; and (e) a combination of any two or more of (a) through (d). When (ii) is (a), (a) has amino hydrocarbyl groups which are secondary or tertiary hydrocarbyl groups; when (ii) is (d), and (d) is an aromatic diimine, each imino hydrocarbylidene group has at least two carbon atoms. Processes for producing polyurethanes, polyureas, and polyurea-urethanes are also provided.Type: GrantFiled: February 16, 2011Date of Patent: December 20, 2011Assignee: Albemarle CorporationInventors: Paul L. Wiggins, John Y. Lee, Judit Orgad

Patent number: 8076518Abstract: This invention provides chain extender compositions. These compositions comprise (i) an aliphatic secondary diamine, and (ii) a component selected from the group consisting of: (a) a cycloaliphatic primary diamine; (b) an aliphatic secondary diamine; (c) an aliphatic secondary diamine and an aliphatic primary diamine; (d) an aliphatic diimine; and (e) a combination of any two or more of (a) through (d), with the proviso that when (ii) is (a), (i) is a noncyclic aliphatic secondary diamine. Processes for producing polyurethanes, polyureas, and polyurea-urethanes are also provided.Type: GrantFiled: September 25, 2006Date of Patent: December 13, 2011Assignee: Albemarle CorporationInventors: Paul L.

Patent number: 7767858Abstract: This invention provides aromatic diimines which have imino hydrocarbylidene groups with at least two carbon atoms, and aromatic secondary diamines which have amino hydrocarbyl groups with at least two carbon atoms. Both the aromatic diimines and the aromatic secondary diamines either are in the form of one phenyl ring, or are in the form of two phenyl rings connected by an alkylene bridge; each position ortho to an imino group or an amino group bears a hydrocarbyl group. When in the form of one phenyl ring, there are two imino groups on the ring or two amino groups on the ring; the imino groups or amino groups are meta or para relative to each other. When in the form of two phenyl rings connected by an alkylene bridge, there is either one imino group or one amino group on each phenyl ring. Also provided are processes for forming diimines and secondary diamines.Type: GrantFiled: September 14, 2007Date of Patent: August 3, 2010Assignee: Albemarle CorporationInventors: Paul L. Wiggins, Judit Orgad, John Y. Lee, Mahmood Sabahi
