<br/><br/> The aim of the present work is to prepare some organic classes of compounds bearing functional groups which can intervene with the chain degradative products , resulting from the thermal and Photo - treatment of the Polymer The stabilizing efficiency of these organic stabilizers (thermal and Photo) will be examined either alone or as co - stabilizers with conventional stabilizers in different proportions
