Jute-reinforced urethane polymer composite under gamma radiation

Some formulations were developed with urethane triacrylate oligomer in comb ination with monomers of different functionalities. Thick (2 mm) polymer fi lms were prepared with these formulations under Co-60 gamma radiation. The films were reinforced with jute by mixing jute particles in the above formu lations at different proportions, These films were characterized and it was observed that both tensile and bending strengths were enhanced by the addi tion of the jute in the formulation; however, elongation reduced with the i ncrease in jute concentration, However, the presence of trimethylol propane triacrylate (TMPTA) in the formulations slightly reduced the tensile prope rties of the composites from the already enhanced properties induced by the TMPTA in the films.
