FIELD: processes for producing composite materials used for making laminate glass.
SUBSTANCE: method comprises steps of co-extrusion of first layer of plasticized polyvinyl butyral and second layer of polyurethane adjacent to first layer in such a way that plasticizing agent may migrate form first layer to second one. It is possible to co-extrude third layer of polyurethane at side of polyvinyl butyral layer opposite relative to second layer. At least second or third layer, preferably both layers have thickness less than 5 mils.
EFFECT: possibility for producing composite materials with enhanced operational properties.
