    Abstract: A laminated sheet product which includes at least one sheet of an absorptive material is made by moistening the absorptive sheet with a liquid polymerizable organic compound and then applying a finely divided thermoplastic polymeric substance in a substantially uniform manner to the faces or one face of the absorptive sheet, the said polymer being at least swellable in said liquid polymerizable composition, then superposing the several sheets and finally subjecting the composite laminate to pressure and elevated temperatures sufficient to cause curing of the polymerizable organic composition and forming of a substantially coherent polymer coating on the sheet. Wood types can thus be used for the laminates which could not be impregnated with polymerizable lacquers. Also, laminates can be made from or including pressed materials and a lamination is possible without the use of the conventional adhesives. Also, decorative outer sheets can be included in the lamination and profiles can easily be formed in a pressing operation. The process is also useful for improving the appearance of one single sheet of products.

    Abstract: SOLID LINEAR OR CROSS-LINKED HYDROXYCARBOXYLIC ACID POLYMERS WHICH IN THE MAIN CHAIN HAVE PREDOMINANTLY CARBON-TO-CARBON BONDS, ALL, OR THE MAJOR PART OF THE UNITS IN THE MAIN CHAIN, HAVING THE FORMULA

    -CH2-C(-R1)(-COO-A)-, AND -CH2-C(-R)(-CH2-OH)-, OR

    -CH2-CH-OH

    WHEREIN R AND R'' ARE THE SAME OR DIFFERENT AND ARE ALKYL HAVING 1 TO 6 CARBON ATOMS OR HYDROGEN AND WHEREIN R1 MAY ALSO BE HALOGEN. IN ADDITION, THERE MAY BE A MINOR AMOUNT, RELATIVE TO THE NUMBER OF THE UNITS (I), (II) AND (III), OF UNITS OF THE FORMULA

    -C(-R)(-COO-A)-C(-R)(-COO-A)-

    WHEREIN A IS HYDROGEN, ONE VALENCE OF A MONOVALENT OR A POLYVALENT METAL OF AMMONIUM. ALL OF THESE UNITS ARE ARRANGED IN RANDOM SEQUENCE AND THEIR NUMBE IS SUCH THAT THE RATIO OF CARBOXYL OR CARBOXYLATE OT HYDROXYL GROUPS IS BETWEEN 1.1 AND 16. THE MINIMUM DEGREE OF POLYMERIZATION IS 3; PREFERABLY, IT IS NOT ABOVE 5000, AND PARTICULARLY BETWEEN 3 AND 600. THE POLYMERS ARE VALUABLE AS COMPLEXING AGENTS.
