1. A polymer material which is a copolymer polymerised at least from:
a) at least one filler material, wherein the filler material is provided in the form of small particles, wherein the average longest cross section of the particles is in the range of 0.1 to 750 μm, and wherein said filler material is provided in the form of a powder, said filler material comprising finely ground barley straw covalently —O-linked to wherein R1 and R2 independently are selected from the group consisting of —H, C1-6 alkyl, C1-6 alcohols, C1-6 alkoxy, C1-6 ethers, halogen and C1-6 alkyl substituted with halogen, wherein said filler comprises a polymer covalently linked to —OH or a long chain alcohol comprising at least 10 carbon atoms; and b) at least one monomer and/or at least one cross-linker, wherein
i) the monomer is a monomer of the general structure or the general structure wherein R1 and R2 independently are selected from the group consisting of —H, C1-6 alkyl, C1-6 alcohols, C1-6 alkoxy, C1-6 ethers, halogen and C1-6 alkyl substituted with halogen and R3 is selected from the group consisting of linear and branched alkyl, alkenyl, alkoxy, ethers, aliphatic ring optionally comprising heteroatoms, alcohols, halogen, alkyl substituted with halogen and —H and
whereinii) the cross-linker is a sugar moiety covalently O-linked to at least two groups,
wherein R1 and R2 independently are selected from the group consisting of —H and C1-6 alkyl,
and wherein said two groups may be identical or different; and c) optionally, at least one plant fiber material, which is covalently —O-linked to wherein R1 and R2 independently are selected from the group consisting of —H, C1-6 alkyl, C1-6 alcohols, C1-6 alkoxy, C1-6 ethers, C1-6 alkenyl, halogen and C1-6 alkyl substituted with halogen. |
