Abstract: A laminate comprising a sheet of polycarbonate laminated to another sheet comprising, on a weight basis, a) 30 to 90% polyvinyl butyral and b) 70 to 10% thermoplastic polyurethane, containing a plasticizing amount of one or more C.sub.2 -C.sub.5 alkanediols or diethylene glycol.

Abstract: A sheet formed of a polyblend comprising, on a weight basis, a) 30 to 90% polyvinyl butyral containing about 11 to 30% hydroxyl groups and b) 70 to 10% thermoplastic polyurethane which is the reaction product of:(i) polyether polyol or a mixture of polyether polyol and polyester polyol; and(ii) aliphatic diisocyanate, aromatic diisocyanate or a mixture of aliphatic and aromatic diisocyanates;the combined percentages of a) plus b) in the polyblend always equaling 100%; such sheet at 0.76 mm thickness having no greater than 2% haze.

Abstract: Multiaxially oriented containers are formed from an extruded, molecularly orientable thermoplastic parison having a programmed wall thickness. The parison while at extrusion temperature is sealed at one end and expanded incrementally in a conditioning mold into the shape of a preform which is allowed to set therein for a brief time period in order to develop an outer skin at reduced temperature. The full wall of the variable thickness preform is then reduced in temperature to within the orientation temperature range and the preform then stretched longitudinally and expanded radially in a finishing mold to develop axial and radial orientation while forming the container. Since the thicker portion(s) of the programmed parison do not cool as much in the conditioning mold as do the thinner portion(s) they consequently subsequently stretch to a greater extent, and this phenomenom must be compensated for in the initial programming step.
