Abstract (en)
[origin: WO2010075530A1] Methods and compositions for making non-woven materials from polyhydroxyalkanoate polymers are provided. In certain aspects, the invention pertains to an extruded fiber comprising a polyhydroxyalkanoate polymer, a wet milled nucleating agent and a plasticizer, wherein the average particle size of the wet-milled nucleating agent is about 20 microns and is dispersed in the polymer.
