主权项 1. A polymer composition (C) comprising: at least one polyester (P) comprising at least 50 mol % of recurring units comprising at least one cycloaliphatic group, at least one white pigment selected from the group consisting of TiO2, ZnS, ZnO, CeO2 and BaSO4, at least one inorganic nucleating agent, and at least one plasticizer having a boiling point of at least 200° C., present in an amount of at least 1 wt. % and at most 4 wt. %, based on the total weight of the polymer composition (C), and selected from the group consisting of phthalate esters, trimellitate esters, benzoate esters, terephthalate esters, citrate esters, cyclohexane diacid esters and esters of oligomers/polymers of ethers.
