A coating formulation including a polymer produced by radical polymerization, wherein said polymer comprises a backbone with one or more monomers, wherein one or more of said monomers comprises one or more hydrophobic side chains, wherein the hydrophobic side chains are alkyl chains with 8 or more carbon atoms, wherein the overall weight of the hydrophobic side chains is at least 20% (w/w %) of the total weight of the polymer; and one or more anti-blocking agents selected from inorganic pigments, polymers with a Tg or Tm of at more than 40° C., or a combination thereof; wherein said coating formulation comprises at least 30% (w/w %) of said polymer, wherein in weight percent of the coating formulation, the amount of the inorganic pigment is from about 10% to 30% and the amount of polymer with a Tg or Tm of more than 40° C. is from about 10% to about 40%.

Polymeric coating formulation with hydrophobic side chains

The present invention relates to a process for making a heat sealable substrate starting from a water repellent substrate. In particular, the present invention relates to a process for making water repellent paper cups. In particular, the present invention discloses a process for applying one or more heat sealable strips on a water repellent substrate, for example paper or paper board. Further, the present invention also relates to a heat sealable substrate obtained by said process for making paper cups.

Paper with water repellent and partially heat sealing properties

A method the preparation of rigid foams by reacting an organic polyisocyanate with an isocyanate-reactive material in the presence of a blowing promoter characterised in that the isocyanate-reactive material comprises at least one isocyanate-reactive cyclic carbonate or isocyanate-reactive cyclic urea, the reaction being performed in the presence of an inert insoluble organic liquid which is present as the dispersed phase of an emulsion or a microemulsion, and in the presence of a metal salt catalyst.
