The kinetics of photodegradation has also been studied. Surface damage caused by polychromatic (&gt;= 290 nm) at 55 degrees C in air is presented in different micrographs. The rate of photodegradation is very fast in terpolymers containing polar monomers as compared with copolymers and polyethylene. Morphological study of these photodegraded samples showed a very good relation with photodegradation results.</p>10afunctional polyolefins10aPhotodegradation10aUV irradiation1 aFernandes, Susete, N.1 aCorreia, Sandra1 aPrasad, A., V.1 aReddy, K., R.1 aRana, S.1 aLonkar, Sunil, P.1 aMarques, Maria, M.1 aSingh, R., P.  uhttps://library.ncl.res.in/content/photodegradation-ethylenepropylenepolar-monomers-co-and-terpolymers-i-prepared-group-4-0
