Abstract
Composite cellulose containing materials which are waterproof and biodegradable are produced which consist essentially of cellulose and hydrophobic polymer-based composition in the amount about 4 to 40 wt %. The polymer-based composition comprises first polymer, which is partially saponified polyvinyl acetate, second polymer, which functions as plasticizer for improving elasticity of the first polymer and cross-linking agent, which is capable to cross-link the first polymer. The polymer-based composition may additionally contain environmentally friendly hydrophobizators, fillers and pigments.
