  • Processable poly(hydroxy acids)
    Patent number: 6559244
    Abstract: A processable poly(hydroxy acid) composition which has been stabilized by adding to the polymer during the melt processing stage 0.05-3% by weight of a peroxy compound the degradation of which produces one or more acid radicals, and which has good melt strength and elasticity. The melt strength is high enough to produce films with conventional methods as the film blowing method.
