POLYESTER-MODIFIED POLYSILOXANES AND THEIR USE AS ADDITIVES FOR THERMOPLASTICS, MOULDING COMPOUNDS AND COATING MATERIALS

摘要

The invention relates to polyester-modified polysiloxanes of the general formula (I) (see formula I) where A is an alkyl group having 1 to 8 carbon atoms, Z is an aliphatic group having 1 to 14 carbon atoms, R is an aliphatic and/or cycloaliphatic and/or aromatic polyester group containing at least 3 (see formulas II and III) and having a weight-average molecular weight of 200 to 4000 g/mol, with no Zerewitinoff hydrogen atoms, Q is a group which contains no Zerewitinoff hydrogen atoms and is free from reactive carbon-carbon multiple bonds, m is 3 to 200 and o + n = 2, with both o and n being other than zero. The invention further relates to the use of the compounds of the invention in thermoplastics, moulding compounds and coating materials.
