ABSTRACT:
Synthetic, substantially water-insoluble organic polymers having a backbone or main chain including repeating units of at least one polymer forming biologically active component such as a pesticide are capable of slowly degrading in the medium where their activity is desired to slowly release the free biologically active component and thereby prolong the period of effectiveness of the biologically active component.
