This invention relates to a polymer composition that is particularly suitable for use in the manufacture of injection moulded articles, which can be biodegraded in industrial composting. This invention also relates to a process for the production of the said composition and articles obtained thereby. The polymeric composition comprises, with respect to the sum of components i.-v.: i) 20-60% by weight of at least one polyester comprising: a) a dicarboxylic component comprising, with respect to the total of the dicarboxylic component: a1) 0 -20% by moles of units deriving from at least one aromatic dicarboxylic acid, a2) 80-100 % by moles of units deriving from at least one saturated aliphatic dicarboxylic acid, a3) 0 - 5 % by moles of units deriving from at least one non-saturated aliphatic dicarboxylic acid; b) a diol component comprising,with respect to the total of the diol component,: b1) 95 - 100 % by moles of units deriving from at least one saturated aliphatic diol; b2) 0- 5 % by moles of units deriving from at least one non-saturated aliphatic diol; ii) 30 - 60 % by weight of at least one polyhydroxyalkanoate; iii) 0.01 - 5% by weight of at least one crosslinking agent and/or chain extender comprising at least one di- and/or polyfunctional compound carrying isocyanate, peroxide, carbodiimide, isocyanurate, oxazoline, epoxy, anhydride or divinylether groups and mixtures thereof; iv) 0 - 10 % by weight of at least one filler; v) 2 - 30 % by weigth of vegetable fibers. |
