This invention relates to a biodegradable polyamide. In particular, this invention relates to a polyamide containing keto carbonyl groups set out in monomeric units along the main chain of the polymer and having the structure -OC-(CH2)n- @-(CH2)m-CO)- (I) wherein n and m are equal or different whole numbers ranging from 8 to 10, preferably 8. Said polyamides are high light-sensitive to the solar U.V. radiation, so that the exposure of the products obtained by means of such polyamides to the U.V. solar radiation causes the product to be transformed into a fragile or friable material, that is biodegradable. |
