  • Publication number: 20080033210
    Abstract: 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.

  • Publication number: 20070270566
    Abstract: 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.

  • Publication number: 20070073030
    Abstract: 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.

  • Patent number: 6850524
    Abstract: A system provides predictive routing of packets in a network with multiple nodes. The system receives messages from the nodes (740). The messages contain predictions regarding future events that may happen to entities associated with the nodes. The system extracts the predictions from the received messages (750), determines active states of the entities based on the predictions (750), and generates a routing table using the active states of the entities (760). The system uses the routing table to route packets through the network.
