Abstract: A laminated glass is provided, which can provide appropriate acoustic preventing performance for each portion of the laminated glass according to the positional relationship between the laminated glass and a passenger, and which employs an interlayer having a functionality. The interlayer has at least one resin layer having a functionality; the thickness of the interlayer at the upper side is from 1.5 to 3 times of the thickness at the lower side; the thickness at the upper side is at least 1.5 mm; the thickness at the lower side is at least 1 mm; the laminated glass has higher functionality in a portion close to a passenger's head (ears) that senses a sound, more than other portions; and the laminated glass can prevent optical distortion due to the interlayer.

Abstract: A mold for preparing window glass provided with a gasket at a peripheral portion of a glass sheet for a window includes, placing a glass sheet in the shaping mold which has two mold parts to provide an inner cavity in which resilient sealing members are attached respectively to the two mold parts so as to come in contact with surfaces of the glass sheet so that a gasket forming cavity is formed at a peripheral area of the glass sheet by the cooperation of the inner cavity of the shaping mold, the resilient sealing members and the glass sheet, the resilient sealing member is then pushed to the contacting surface constituted by the resilient sealing member and a part of the shaping mold in the inner cavity via a pushing means after the assembling of the shaping mold. The glass sheet, and a gasket material is then injected into the gasket forming cavity to form a gasket.

Abstract: A process for making a glazing product which includes forming a gasket on a sheet of bilayer glass with a self healing transparent elastic plastic layer bonded to one side of the glass. A removable protective material is applied to the plastic layer. The assembly is placed in a mold cavity and a plastic material is injected into the mold cavity to form a gasket. The protective material is removed from the plastic layer after the gasket has formed.

Abstract: A process for producing a shaped article of a non-cellular or microcellular polyurethane elastomer by reaction injection molding by using a high molecular weight active hydrogen compound component (A), a chain extender component (B) and a polyisocyanate compound component (C) as starting materials,wherein(I) the high molecular weight active hydrogen compound component (A) comprises(1) at least one polyoxyalkylene polyol (a-1) having an average molecular weight per hydroxyl group of from 800 to 4000 and an average number of hydroxyl groups per molecule of from 2 to 8 and containing at least 5% by weight of oxyethylene groups at the terminal portions of its molecules,(2) a high molecular weight amine (a-2) having from 2 to 8 active hydrogen-containing groups, and optionally(3) a high molecular weight polyol (a-3) other than the polyalkylene polyol (a-1), and(II) the chain extender component (B) comprises(1) a low molecular weight polyol (b-1) having from 2 to 4 hydroxyl groups and a molecular weight of at most
