Composition comprising polyester and polyolefin

An article comprising a stud for fitting into a complementary receptacle and/or comprising a receptacle for fitting into a complementary stud comprising a composition comprising A) a polyester, B) a polyolefin and C) a compatibilizer, wherein

• the amount of A) is at least 75 wt % of the total composition,
• the amount of B) is 5 to 22.5 wt % of the total composition and
• the weight ratio of the amount of B) with respect to the amount of C) is 2 to 20,
• wherein A) is polyethylene terephthalate having a density of at most 1.35 g/cm3 as determined according to ISO 1183, and
• B) is selected from the group consisting of
• a low density polyethylene having a density of 0.916 to 0.940 g/cm3 according to ISO1183 and a melt flow index of 0.1 to 10.0 g/10 min, measured in accordance with ASTM D1238 using a 2.16 kg weight and at a temperature of 190° C.,
• a linear low density polyethylene having a density of 0.915 to 0.940 g/cm3 according to ISO 1183 and a melt flow index of 0.1 to 5 g/10 min, measured in accordance with ASTM D1238 using a 2.16 kg weight and at a temperature of 190° C.,
• a high density polyethylene having a density of 0.940 to 0.970 g/cm3 according to ISO1183 and a melt flow index of 0.1 to 15 g/10 min, measured in accordance with ASTM D1238 using a 2.16 kg weight and at a temperature of 190° C., and
• an elastomeric copolymer of ethylene and an α-olefin having 4 to 10 carbon atoms having a melt flow index of 3.0 to 8.0 g/10 min, measured in accordance with ASTM D1238 using a 2.16 kg weight and at a temperature of 190° C.
