Abstract

• This work is mainly concerned with the preparation of polymeric material from cellulose acetate with polyvinyl alcohol (PVA)) and glutaraldehyde as used as cross linker and the study of their characteristics. The films were prepared by mixing various proportions of cellulose acetate with various proportions of polyvinyl alcohol and fixed proportion of glutaraldehyde by blending, casting technique. The prepared films were investigated according to physicomechanical parameters such as thickness, tensile strength, elongation at break, tear strength and physicochemical parameters such as water uptake and swelling properties. The optimum ratios for preparing films were chosen according to their physicomechanical properties. The most favorable conditions for preparing film namely CPF 3 was found to be 20 mL of 2 % w/v cellulose acetate, 80 mL of 4 % w/v PVA and 25 mL of 0.025 M glutaraldehyde. It was found that the film CPF 3 possessed 27.30 MPa of tensile strength, 24.60 % of elongation at break and 58.90 kNm-1 of tear strength. All prepared films showed plain, clear, smooth surface, flexible, highly transparent and light white colour. The prepared films can be used in packaging materials.
