Abstract: A method for producing fibers and films comprising emulsion polymerizing a polyvinyl alcohol derivative having sulfone or sulfate group with a chlorine-containing vinyl monomer, adding the thus formed emulsion to a matrix of polyvinyl alcohol and then coagulating the mixture into a film or fiber. The resulting polymeric compositions are composed of polyvinyl alcohol, the sulfone or sulfate-containing polyvinyl alcohol and the chlorine containing vinyl polymer, in which a part of the chlorine-containing vinyl polymer is grafted onto the polyvinyl alcohol derivative. The emulsions used possess excellent stability and the films and fibers therefrom possess excellent heat resistance.
Abstract: A laminated decorative sheet is prepared by applying a coating layer consisting of a thermo-setting resin composition on a base paper for a decorative laminate which has been prepared by incorporating a composition the whole or a major part of which is composed of a synthetic rubber and/or a thermo-plastic synthetic resin substance into the base paper during the paper making thereof or by impregnating the base paper with the thermo-plastic synthetic resin composition or with the mixture thereof; or alternatively is prepared by laminating another base paper for a decorative laminate which has been impregnated with the thermosetting resin composition on the above mentioned base paper containing the thermo-plastic synthetic resin composition, and the thus prepared layers are laminated under heat and pressure to form a laminated decorative sheet having smooth surface which is subjected to emboss-processing under a heating condition of at least 100.degree.
