2. Reaction Mechanism between Chitosan and Cerium(VI) Ammonium Nitrate for Production of a Greener Poly(Vinyl Acetate) Adhesive
University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)Abstract : Poly(vinyl acetate) (PVAc) has a major application as an indoor wood adhesive. Low water stability is however, one of the greatest drawbacks of PVAc. By grafting PVAc from a chitosan (CS) backbone (CS-graft- PVAc) water stability of adhesive is increased while good mechanical and adhesive properties are retained. READ MORE
