Patent ID: 7462684

Claim:
A process for forming a multilayered, shaped article, comprising: (A) heating a first component to a temperature of about Tg+100° C. to about Tg+300° C. of said first component, said first component comprising at least one polyester which comprises: (a) diacid residues comprising about 95 to about 100 mole percent, based on the total diacid residues, of the residues of terephthalic acid; and (b) diol residues comprising about 15 to about 40 mole percent, based on the total diol residues, of the residues of 2,2,4,4-tetramethyl-1,3-cyclobutanediol; and about 60 to about 85 mole percent of the residues of 1,4-cyclohexanedimethanol; wherein said polyester has an inherent viscosity of about 0.55 to about 0.75 dL/g; (B) heating a second component to a temperature of about 290° C. to about 310° C., said second component comprising a transamidized, homogeneous blend of (a) a polyamide having diamine and diacid residues and comprising about 100 mole percent, based on the total diamine residues, of the residues of m-xylylene diamine and about 100 mole percent, based on the total diacid residues, of the residues of adipic acid; and (b) at least one polyamide selected from nylon 6 and nylon 6,6; (C) forming a shaped article having said first and second polymer compositions in separate layers; (D) recovering scrap first and second components; (E) grinding said scrap first and second components to produce a regrind; (F) optionally, drying said regrind; and (G) combining said regrind with said first component, second component, or a combination thereof, of steps (A) and (B); wherein said second component of step (B) and said first component of step (B) have a difference in refractive index, RI(second component)−RI(first component), of about 0.006 to about −0.0006, and said shaped article has a percent transmittance of at least 75%, and a haze of 10% or less.
