Gela.in films were prepa.ed by ca.ting. Tensile strength (TS) a.d elonga.ion a. brea. (Eb) of the gela.in films were found to be 46 MPa.a.d 3.5%, respectively. Effect of ga.ma.ra.ia.ion (Co-60) on the thermo-mecha.ica. properties of the gela.in films wa. studied. 2-hydroxyethyl metha.ryla.e (HEMa. wa. a.ded to the gela.in during ca.ting va.ying (10% - 30% by weight) a.d found to increa.e the TS significa.tly. Then the films were irra.ia.ed a.d found further increa.e of TS. Thermo-mecha.ica. properties of HEMa.blended gela.in films were compa.ed with those of the pure gela.in films. The coefficient of therma. expa.sion of the gela.in/HEMa.films were a.so mea.ured using thermo mecha.ica. a.a.yzer a.d found opposite trend with compa.ison of gla.s point.

Composites ba.ed on jute fa.rics a.d polypropylene wa. fa.rica.ed by hea.-press molding technique. The mecha.ica. properties of the composites such a. tensile strength, tensile modulus, bending strength, bending modulus a.d impa.t strength were mea.ured in dependence of fiber contents. In order to improve fiber-ma.rix intera.tion, jute fa.rics were trea.ed with a.ueous solutions of K2Cr2O7 (0.005-0.05% w/v). Composite prepa.ed with 0.02% K2Cr2O7 trea.ed jute fa.rics showed the highest va.ues of the mecha.ica. properties. Thermogra.imetric (TG/DTG) da.a.of PP, jute fa.rics a.d composites showed tha. therma. degra.a.ion tempera.ures of composites shifted to higher tempera.ure regions compa.ed to PP or jute fa.rics. Trea.ment of jute fa.rics improved the therma. sta.ility of the composite considera.ly. Sca.ning electron microscopic ima.es of tensile fra.tured sides of untrea.ed a.d trea.ed composites illustra.ed tha. better fiber-ma.rix interfa.ia. intera.tion occurred in trea.ed composite. The rela.ive tendency of wa.er a.sorption of both untrea.ed a.d trea.ed composites wa. a.so explored.
