N2 - The effect of chemo-enzymatic hydrophobisation of spruce chemi thermo mechanical pulp, CTMP, on the properties of biocomposites was studied. CTMP surface was modified with tailor-made phenolic compounds with different alkyl chain length substituents suited to physical properties of plastic. Dispersion technology was developed and applied for dosing these water insoluble substrates. The modified fibre materials were compounded with polylactic acid (PLA) or polyhydroxybutyrate (PHB) and the properties of composites were studied. Modification with dodecyl gallate (DOGA) resulted in improved dispersion of fibres both with PLA and PHB. In addition, mechanical properties were found to be similar or better than with reference fibre containing materials, but depending on the biopolymer type and its' melt behaviour. The enhancement to mechanical properties was found to be more significant in biocomposites in which PLA was used as matrix polymer.
