摘要： The invention is directed to the method, products and apparatus for the manufacture of a high optical quality sheet of plastic comprising a polyurethane layer having energy-absorbing properties obtained by reactive pouring or reactive pulverization of the reaction components.In accordance with the invention, the polyurethane layer is treated, while it is in a state of ongoing polymerization corresponding to an NCO/CH ratio of less than 0.7, with water in a liquid or vapor form and then subsequently, after rolling with an interpolated film, stocking and unrolling, the layer is subjected to heat treatment.

摘要： A high optical quality transparent plastic sheet having a polyurethane layer formed by reactive pouring or reactive pulverization onto a flat horizontal support of a reaction mixture containing a polyol component and an isocyanate component, with the surface of the polyurethane layer which was facing the support during the formation of the layer containing an acrylic polymer resulting from the contact, during deposition of the reaction mixture, of the reaction mixture with a thin acrylic layer previously deposited on the support. The acrylic layer and the polyurethane layer are interpenetrated.
