Abstract: Disclosed is a process for modifying polyamide polymers by attaching a modifying group to the amide nitrogen atoms and the modified product formed. The process comprises contacting a modifier with a diamine then reacting the resulting modified diamine with diacid to form the modified polyamide.

Abstract: The present invention concerns a process a process for making polyester containing up to 50 percent by weight transparent recycled waste polyester by a novel equilibrium depolymerization process. The equilibrium depolymerization process of the present invention for making polyester containing transparent waste polyester comprises the steps of providing a stream containing oligomers, feeding transparent polyester waste to an extruder, melting in said extruder said waste polyester, extruding said molten polyester into said stream containing oligomers, completing the esterification creating a prepolymer mixture, and polymerizing said prepolymer mixture thereby producing polyester containing waste transparent polyester suitable for food grade applications. The present invention meets or exceeds the Food and Drug Administration (FDA) requirements for food contact with polyester and is thus useful in food contact applications, for example beverage containers and polyester film wrap.

Abstract: A fluid distribution device (12) for distributing cleaning fluid to the floor surface comprises a hollow tube extender (56) attached to a hollow fixed shaft (52). A hub assembly (58) having a plurality of hollow open-ended spokes (60, 1-5) is rotatably mounted to the tube extender (56). If used with a brush floor cleaning apparatus a portion of each spoke extends into and terminates within a radial passage (42, 1-5) in the brush (32).
