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.

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.

Abstract: The preset invention relates to low odor ADMA (alkyldimethylamine) products, a process for purifying malodorous impure ADMA products, purified ADMA products, products produced by the purification process, and the use of and the use of the ADMA products as synergists in photopolymerization reactions.

Abstract: A apparatus for the control of a transmission and throttle of a forklift or the like to provide simultaneous control of a transmission position and the throttle position.The apparatus includes a reciprocally and rotatably moveable control rod and a transmission control lever oppositely reciprocable from a neutral position to forward and reverse displacement positions, coupled to and responsive to the movement of the control rod in first and second translational passageways. A throttle control lever is also coupled to and responsive to the movement of the control rod for controlling the throttle responsive to movement of the control rod in the first and second translational passageways and in a third translational passageway. The third translational passageway is defined by first and second wall members which are substantially parallel. The first and second passageways are formed by the first wall member and a fourth wall member and the second wall member and a third wall member respectively.
