Disclosed is a method for preparing polyoxazolidones wherein an ether of a bisanhydrohexitol is reacted with a diisocyanate under conditions which form polyoxazolidones. Preferred bisanhydrohexitols include isoidide, isomannide and isosorbide. The polyoxazolidones are highly crosslinked, rigid, and have high solvent resistance.

Polyoxazolidones derived from bisanhydrohexitols

Multilayer laminates including films, sheets, preforms, containers and other articles having at least one wholly aromatic, amorphous, stretchable liquid crystalline polymer layer with at least one non-polyester thermoplastic polymer layer are provided as well as methods for producing and stretching the multilayer articles. The laminates are suitable for thermoforming and stretch blow molding applications and may be stretched at temperatures lower than the molten state of the liquid crystal polymer and at high total draw ratios without fractures or tears. Containers suitable for food or beverage products may be produced from the laminates.
