Chaclas succeeds Curt Shaw who is retiring at year end.

“We are extremely pleased to name a Chief Legal Officer with Angelo’s strategic understanding of Trinseo’s businesses and the chemical industry,” said Chris Pappas, President and CEO of Trinseo. “His vast experience working across geographies and functional areas will be an asset to support our ongoing activity in capital markets, transactions, compliance, governance, intellectual property and other operational activities of the company worldwide.”
