Patent ID: 7955674

Claim:
A polymer composition, comprising an immiscible blend of: (i) a first component comprising at least one polyester which comprises: (a) diacid residues comprising about 70 to about 100 mole percent, based on the total diacid residues, of the residues of terephthalic acid; 0 to about 30 mole percent of the residues of at least one modifying aromatic dicarboxylic acid having up to 20 carbon atoms; and 0 to about 10 mole percent of the residues of at least one modifying aliphatic dicarboxylic acid having up to 16 carbon atoms; and (b) diol residues comprising about 1 to about 99 mole percent, based on the total diol residues, of the residues of 2,2,4,4-tetramethyl-1,3-cyclobutanediol; and about 1 to about 99 mole percent of the residues of 1,4-cyclohexanedimethanol; and (ii) a second component comprising a homogeneous, transamidized blend of at least two polyamides; wherein said second component (ii) and said first component (i) have a difference in refractive index, RI(second component)−RI(first component), of about 0.006 to about −0.0006, and said immiscible blend has a percent transmittance of at least 75%, and a haze of 10% or less.
