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-4-002030nas a2200289   4500008004100000022001400041245011700055210006900172260007600241300001400317490000800331520102100339653002101360653001301381653002101394653001901415653001401434100002601448700002001474700001601494700002301510700002001533700002001553700001801573700001801591856013101609       2007                        eng d  a0021-899500aPhotodegradation of ethylene/propylene/polar monomers, Co-, and terpolymers.

The polar monomers used to synthesize co- and terpolymers of ethylene/propylene/polar monomer were 5-hexen-1-ol, 10-undecen-1-ol, acrylamide, methylmethacrylate, acrylonitrile, and methylvinyl ketone. The morphological changes of the irradiated samples were determined by scanning electron microscopy. The photodegradation kinetics has also been studied. The surface damage caused by polychromatic irradiation (lambda &gt;= 290 nm) at 55 degrees C in atmospheric air is presented in different micrographs. The rate of photo-oxidative degradation is very fast in terpolymers containing polar monomers as compared with copolymers and homopolymers. The morphological study of the photodegraded samples showed a very good correlation with the photodegraded results.
