Polyesters colored with the residue of heat stable anthraquinone compounds |
| abstract |
Disclosed are colored polyester compositions comprising a polyester having reacted therewith or copolymerized therein at least one residue of an anthraquinone compound having formula (I), wherein AQ is the residue of a 9,10-anthraquinone radical; R?1 and R?2 are the same or different and are unsubstituted or substituted alkyl, cycloalkyl or aryl; X is a group reactive with at least one of the functional groups of the monomers from which the polyester is prepared; and n is 1 or 2. The described anthraquinone compounds possess improved thermal stability and thus are not decomposed at the high temperatures at which polyesters are prepared. Also disclosed are shaped articles, particularly containers, fabricated from the colored polyester compositions. |
