Abstract:
A composite material comprising a cellulose component and a polymer-based component, wherein said polymer-based component is formed using a mixture of:a) a first polymer comprising polyvinyl acetate latex which contains 2-8 wt. % free hydroxyl groups;b) a second polymer comprising a non cross-linked latex selected from the group consisting of poly-(C.sub.2 -C.sub.4)-alkylacrylates, copolymers of vinyl with (C.sub.2 -C.sub.4)-alkylacrylate and -copolymers of (C.sub.2 -C.sub.4)-alkylacrylate with (C.sub.2 -C.sub.4)-alkylmethacrylate, said second polymer providing improved elasticity to the first polymer upon adding the second polymer thereto; andd) a cross-linking agent.
