Abstract
A polymeric blend composition comprising: (a) from about 1 to about 99 wt. % of a polymer; and (b) from about 1 to about 75 wt. % poly alpha-1,3-glucan is disclosed. The addition of alpha-1,3-glucan as a polymer filler can increase the tensile modulus, tensile strength and oxygen barrier properties of the polymeric blend composition.
