Biodegradable articles such as diaper topsheets, diaper backsheets, garbage bags, tampon applicators, disposable syringes and the like that are made from trans-1,4-polyisoprene and like trans-polymers. These articles can also be made from blends of these trans-polymers with other biodegradable components such as starch.
