Process for the preparation of transparent shaped articles

A process for forming a shaped article, comprising:

• (A) melt blending
• (i) a first component comprising at least one polyester comprising:
• (a) diacid residues comprising at least 80 mole percent of the residues of at least one dicarboxylic acid selected from the group consisting of terephthalic acid, isophthalic acid, naphthalenedicarboxylic acid, and 1,4-cyclohexanedicarboxylic acid, and 0 to about 20 mole percent of the residues of at least one dicarboxylic acid having 2 to 20 carbon atoms, each based on the total moles of diacid residues;
• and (b) diol residues comprising at least 80 mole percent of the residues of at least one diol selected from the group consisting of ethylene glycol, 1,4-cyclohexanedimethanol, neopentyl glycol, diethylene glycol, 1,3-propanediol, 1,4-butanediol, and 2,2,4,4-tetramethyl-1,3-cyclobutanediol, and from 0 to about 20 mole percent of the residues of at least one diol having from 3 to 16 carbons, each based on the total moles of diol residues;
• and
• (ii) a second component comprising a homogeneous, transamidized blend of at least two polyamides;
• wherein said first component (i) and said second component (ii) form an immiscible blend, 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;
• (B) forming a shaped article;
• (C) recovering a scrap polymer composition comprising said blended first and second components (i) and (ii);
• (D) grinding said scrap polymer composition to produce a polymer regrind;
• (E) optionally, drying said scrap polymer composition;
• and
• (F) combining said polymer regrind with said first and second components (i) and (ii) of step (A).
