Abstract: The present invention relates to the high-sensitivity thermosensitive multilayer film and the method to produce plate-making paper using the film. In the present invention, the high-sensitivity thermosensitive multilayer film consists of at least one functional layer and at least one peeling layer. The said functional layer is made of the thermoplastic resin layer with the thickness of 0.1 to 12 .mu.m and with at least 30% of a thermal shrinkage rate and at least 50 g/mm.sup.2 of thermal shrinkage stress value. The peeling layer consists of the thermoplastic resin layer which is different from that of the functional layer and is the special multilayer film which is readily releasable and capable of exerting a compressive force to the functional layer. When the stencil sheet is manufactured by using the said multilayer film, the operation efficiency at time of lamination and the shrinkage capacity can improve by peeling the said peeling layer after lamination from porous supporting member.

Abstract: Disclosed by this invention are polybenzimidazole polymer/superabsorbent polymer articles. These articles are prepared by either mixing the superabsorbent polymer particulates with the polybenzimidazole polymer solution during the formation of the polybenzimidazole article, or forming a composite of a polybenzimidazole film or fiber material layer with a superabsorbent polymer particulate containing layer. These polybenzimidazole products, either with the superabsorbent polymer particulates interspersed within their structure of as composites, absorb large amounts of fluid while retaining the flame retardancy and chemical unreactivity of conventional polybenzimidazole materials.

The construction may further comprise an adhesive on the bottom and a top marking indicium layer comprising a polymeric binder in which is partially embedded a multiplicity of retroflective lens elements, e.g., transparent microspheres.

Abstract: A process of forming buoyant structures is disclosed, whereby a manifold is positioned in a buoyant structure mold so as to define a space therein that is devoid of buoyant bodies. The mold can then be filled with a resin/microsphere mix that meets minimal resistivity in the devoid space along the length of the manifold. A reduction in mold fill-time is achieved. The resulting buoyant bodies exhibit improved quality.

Abstract: A laminated structural panel which is especially well suited for the construction of a bulkhead used to partition a trailer or other cargo container. The center of the panel is formed by a polyurethane foam core panel sandwiched between a pair of flexible plastic reinforcing sheets adhesively bonded to opposite sides of the core panel. Additional layers of foam are adhesively bonded to the reinforcing sheets, and the outer foam layers are covered by puncture and abrasion resistant skins which are adhesively bonded to the foam. The reinforcing sheets provide the structural foam with tensile strength and with both beam and column strength because of their ability to resist being stretched. The outer foam layers provide impact resistance and enhanced strength due to the effect of the added laminations.
