Abstract
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.
Claims21
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,
- wherein B) is an elastomeric copolymer of ethylene and 1-octene and the elastomeric copolymer has a density of 0.85 to 0.91 g/cm3 according to ASTM D792.
A composition comprising:
- A) a polyester comprising
- a first polyester derived from an aromatic dicarboxylic acid, ethylene glycol and 1,4-cyclohexane dimethanol or is derived from the aromatic dicarboxylic acid, ethylene glycol diol and spiroglycol, and
- a second polyester different from the first polyester, the second polyester comprising polyethylene terephthalate;
- wherein the amount of the first polyester is 10 to 50 wt % of the total weight of the polyester in the composition and the amount of the second polyester is 50 to 90 wt % of the total weight of the polyester in the composition,
- B) an elastomeric copolymer of ethylene and 1-octene and the elastomeric copolymer having a density of 0.85 to 0.91 g/cm3 according to ASTM D792, and
- C) a compatibilizer comprising a copolymer of ethylene and glycidylmethacrylate,
- wherein the amount of A) is at least 75 wt % of the total composition,
- the amount of B) is 8 to 15 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.
