摘要:
Disclosed are clear blends comprising:(A) from 1 to 99 percent by weight of a polycarbonate comprising a diol component comprising from 90 to 100 mol percent 4,4'-isopropylidenediphenol units and from 0 to 10 mol percent modifying diol units having 2 to 16 carbons, wherein the total mol percent of diol units is equal to 100 mol percent; and(B) from 1 to 99 percent by weight of a polyester comprising(a) a dicarboxylic acid component comprising from 80 to 100 mol percent dicarboxylic acid units selected from the group consisting of terephthalic acid units, isophthalic acid units, and mixtures thereof; and from 0 to 20 mol percent modifying dicarboxylic acid units having about 2 to 20 carbons, wherein the total mol percent of dicarboxylic acid units is equal to 100 mol percent; and(b) a glycol component comprising from 30 to 99 mol percent 2,2,4,4-tetramethyl-1,3-cyclobutanediol units, from 1 to 70 mol percent ethylene glycol units, and from 0 to 10 mol percent modifying glycol units having from 3 to 16 carbons, wherein the total mol percent of glycol units is equal to 100 mol percent;wherein the total units of said polyester is equal to 200 mol percent;wherein said blend is clear and the total weight percent of said polycarbonate (A) and said polyester (B) is equal to 100 weight percent.
