摘要： A method for preparing a polymeric laminate by the reactive coextrusion of functionalized polymers wherein at least one layer is a polymer having functional groups and the adjacent layer is a polymer having coreactive groups which form covalent bonds with the functional groups at the interfacial surfaces. One such functional group can comprise a pendant cyclic imino ether group to form covalent bonds with the coreactive groups. A laminate having a plurality of layers covalently bonded together through the interaction of pendant cyclic imino ether groups and coreactive groups is also provided.

摘要： Improved films that contain molecular composites or block copolymers of lyotropic liquid crystalline polymer and thermoplastic polymer can be made by the steps of:(1) washing a dope film, that contains a solvent and the molecular composite or block copolymer;(2) stretching the wet, never-dried film from Step (1) in at least one direction; and(3) drying the film from Step (2).The films have improved mechanical properties and can be used in structural applications.

摘要： An apparatus for the constrained drying and/or heat treating of a continuous or roll of, web stock of film. This apparatus includes a mechanism which grasps a film by its edges and moves said film through a drying zone, with said mechanism holding said film taut without substantial stretching of said film in the drying zone, and a means to remove the evaporated solvent from said apparatus. The apparatus is particularly useful for drying film of polybenzoxazole, polybenzothiazole and copolymers thereof, as well as molecular composite films. A method of drying/heat treating film is also disclosed.
