Abstract: The present invention concerns a homogenous polymer mixture comprising a polymer composition that comprises at least one cellulose ester polymer, which is cellulose acetate propionate (CAP), and at least one other polymer selected from the group consisting of polybutylene succinate (PBS) and polypropylene succinate (PPS), wherein the total amount of said cellulose ester polymer and said at least one other polymer is at least 80 wt. % based on the total weight of the polymer composition. The invention also concerns a method and use related thereto.

Abstract: The invention concerns a method of manufacturing paper or board, the paper or board obtained by the method, and a method of producing a tray from the board. In a fibrous stock for papermaking is incorporated an amount of polymer coated fibrous particles, which even have a foaming agent such as moisture contained therein. A web is formed from the fibrous stock on a forming fabric of a paper or board machine, followed by pressing and drying to a finished paper or board. As the paper or board is sufficiently heated the foaming agent within the particles evaporates, causing expansion and foaming of the polymer coating, which adds to malleability of the board as it is moulded into a shaped article such as a board tray. The invention even covers production of doubly coated fibrous particles for use in said methods, the inner coating layer being of a foamable polymer with a higher melt flow rate and the outer coating layer being of a non-foaming polymer of a lower melt flow rate.

In the method an esterified hemicellulose is provided wherein at least a part of the esterifying groups are derived from a lower alkanoic acid; the esterified hemicellulose is dissolved in an alkanoic acid to produce a solution; and the solution is dispersed into water to produce an aqueous dispersion of the hemicellulose ester. The present compositions, containing hemicellulose derivatives of low solubility, can be used in paper, paperboard and other fibre-based materials, for paints, surface treatments for polymer films, and polymer films as such, and can be applied as binders.
