  • Patent number: 11572444
    Abstract: The invention is directed to a process for the continuous acetylation of wood elements. The process particularly combines a batchwise impregnation step, with a continuous reaction step. In order to realize this, a collection step is built-in, so as to allow batches of impregnated wood elements to be fed into a reactor in a continuous manner. Very high acetylation contents can be obtained, at a level that had not been achievable before in a continuous and non-catalyzed acetylation process.

  • Patent number: 8541542
    Abstract: The present invention relates to a process for reducing residuals content in a vinyl aromatic polymer, said residuals comprising essentially unpolymerized vinyl aromatic monomer, wherein the vinyl aromatic polymer in the molten state is brought in contact with a solid in powder capable to catalyze the alkylation of said residual vinyl aromatic monomer on the vinyl aromatic polymer. Advantage of the present invention is a sharp reduction of the unpolymerized vinyl aromatic monomer in the vinyl aromatic polymer without generating a new residual and without inducing a colored vinyl aromatic polymer. The present invention also relates to said vinyl aromatic polymer having a low residuals content.

  • Patent number: 5501902
    Abstract: A portable material having first and second surfaces, which printable material includes a first layer defining the first surface and a second layer defining the second surface. The second layer includes particles of a thermoplastic polymer having largest dimensions of less than about 50 micrometers and from about 10 to about 50 weight percent of a film-forming binder, based on the weight of the thermoplastic polymer. When the second layer has a melting point of from about 65 to about 180 degrees Celsius, the printable material is suitable for use as a heat transfer material. Desirably, the second layer also contains from about 2 to about 20 weight percent of a cationic polymer, based on the weight of the thermoplastic polymer. Other components which can be contained in the second layer include from about 1 to about 20 weight percent of a humectant; from about 0.2 to about 10 weight percent of an ink viscosity modifier; from about 0.1 to about 5 weight percent of a weak acid; and from about 0.

  • Patent number: 5487950
    Abstract: The invention relates to the lacquering of polar film substrates with a coating system consisting of several components, the single application of material resulting in a multilayer structure of the lacquer coat. The coating system is preferably aqueous and free from organohalogen and results in an improved barrier action of the films against water vapor.

  • Patent number: 5486436
    Abstract: A web or sheet product is provided which is coated on at least a portion of its surface with a bond-enabling material for adhering toner particles, on the surface of the sheet. The sheet product can be used as a mailer or confidential form which is sealed using toner particles as the adhesive. The bond-enabling material may be a polymer which is coated on the sheet as a liquid and then cured to form a film on the surface of the sheet. The bond-enabling material is resistant to melting or degrading when exposed to temperatures used for fusing toner particles, and additionally may act as a tie coat to enhance the adhesion of toner particles to the surface of the sheet. The bond-enabling material may be coated on the peripheral edges of the sheet, and toner particles are printed over the bond-enabling material on the peripheral edges of the sheet. The sheet is folded and sealed by the application of heat and pressure to the edges of the sheet.
