Abstract
The invention relates to a polymer material with several advantageous properties. The polymer material has a low degree of swelling in water, it is biodegradable, it has extremely low permeability to gasses such as CO2 and it has a high strength. The polymer material is useful for a number of purposes, such as for preparing containers for food or beverages. The polymer material is prepared from a prepolymerization mixture comprising grafted plant derived material and monomers and/or cross-linkers.
