can be easily degraded. a well known co-polymer is biopol. it is a random co-polymer with blocks of phb and blocks of poly(hydroxypentanoate), (often known as polyhydroxyvalerate, phv). like other phas, the film is used to wrap foods, coatings for paper and cardboard, kitchen ware (cups, saucers, plates
uses, all the ethanoate groups are hydrolyzed to form hydroxyl groups (fully hydrolyzed pva): however, for other uses, only partially hydrolyzed pva is used. pva is a readily degradable water-soluble polymer and among its uses are as an adhesive (paper, fabrics, leather) and for coating paper and paperboard...
