چکیده
|
Soft coating photocrosslinkable elastomers were prepared by addition of photosensitive alcohol to epoxidized 1,4-polyisoprene (20% epoxidized units of 1,4-polyisoprene e20 and 38% epoxidized units of 1,4-polyisoprene e38). the reaction was carried out in mild conditions in the presence of cerium ammonium nitrate can as catalyst and the yield in alkoxylated units averages 40% for 90% conversion of epoxidized units. the obtained polymers were characterized by ir,1h nmr and uv-vis. spectroscopic techniques. thin films obtained by casting technique were irradiated by uv light to undergo photocrosslinking reaction and the efficiency of the photocrosslinking process was monitored by uv-vis analysis of the irradiated samples.
