The invention relates to a composition comprising A) a polyester, B) a polyolefin and C) a compatibilizer, wherein A) comprises a first polyester derived from an aromatic dicarboxylic acid, an acyclic aliphatic diol and at least one of a cycloaliphatic diol and spiroglycol and a second polyester different from the first polyester. The invention further relates to an article comprising the composition, particularly a toy block. 1. A composition comprising A) a polyester , B) a polyolefin and C) a compatibilizer , wherein A) comprises a first polyester derived from an aromatic dicarboxylic acid , an acyclic aliphatic diol and at least one of a cycloaliphatic diol and spiroglycol and a second polyester different from the first polyester.2. The composition according to claim 1 , wherein the amount of the first polyester is 1 to 95 wt % of the total weight of the polyester in the composition and the amount of the second polyester is 5 to 99 wt % of the total weight of the polyester in the composition.3. The composition according to claim 1 , whereinthe aromatic dicarboxylic acid is selected from isophthalic, terephthalic acid, 1,2-di(p-carboxyphenyl)ethane, 4,4′-dicarboxydiphenyl ether, 4,4′-bisbenzoic acid,1,4- or 1,5-naphthalene dicarboxylic acids, and mixtures thereof, and/orthe acyclic aliphatic diol is selected from ethylene glycol, propylene glycol, 2,2-dimethyl-1,3-propane diol, 2-ethyl, 2-methyl, 1,3-propane diol, 1,4-butanediol, 1,3- and 1,5-pentane diol, dipropylene glycol, 2-methyl-1,5-pentane diol, 1,6-hexane diol, triethylene glycol, 1,10-decane diol, and mixtures thereof, and/orthe cycloaliphatic diol is selected from the group consisting of dimethanol decalin, dimethanol bicyclo octane, 1,4-cyclohexane dimethanol, and mixtures thereof.4. The composition according to claim 1 , wherein the first polyester is derived from the aromatic dicarboxylic acid claim 1 , ethylene glycol and 1 claim 1 ,4-cyclohexane dimethanol or is derived from the aromatic ...
