Abstract
Compositions are provided which are useful in the production of polymeric products, such as coatings and films, which comprise branched PHA. The compositions of the invention comprise PHA and 0.001-0.5 wt. % of a free radical initiator. The invention further provides methods of using the compositions for the efficient and cost effective production of films and coatings by reducing draw resonance and neck-in behavior of extruded PHAs.
