The objective of the work described was to study the preparation of a novel polymer composite from gelatin (GT), natural rubber (NR) and bagasse cellulose (BC) using potassium persulphate as an initiator, and urea (U) as a plasticizer. The results showed that the moisture content, moisture absorption and swelling ratio decreased as a function of the BC content in the polymer composite. Further, the moisture content and the moisture absorption tended to increase with increasing U content, while the contact angle of the sample decreased with increasing U. The highest elongation at break was found with 2% BC. Moreover, the elongation at break and swelling ratio was also enhanced after the addition of U, and good BC dispersion in the polymer matrix was also confirmed by SEM. Finally, the biodegradation of the GT/NR composite was around 60% after burial in natural soil for 30 days.
