Abstract
A composition includes thermoplastic polymers and at least one organosilicon compound of the general formula R3-a-b(OR1)aR2bSi[OSiR2]p[OSiRR2]q[OSiR22]rOSiR3-a-b(OR1)aR2b (I), wherein a+b is ≤3 and at least one R2 radical is present.

A composition comprising
- (A) A thermoplastic polymer, and
- (B) at least one organosilicon compound of the formula
- R3-a-b(OR1)aR2bSi[OSiR2]p[OSiRR2]q[OSiR22]rOSiR3-a-b(OR1)aR2b (I),
- where
- R are each identical or different and are monovalent, SiC-bonded hydrocarbon radicals having 1 to 6 carbon atoms,
- R1 are each identical or different and are hydrogen or monovalent, optionally substituted hydrocarbon radicals,
- R2 is an SiC-bonded unit of the formula
- R3—X—[CO—CO]—X—R4— (II)
- where
- X is —NRx—,
- R3 are each identical or different and are monovalent, optionally substituted hydrocarbon radicals having at least 6 carbon atoms,
- R4 are divalent, optionally substituted hydrocarbon radicals having 1 to 40 carbon atoms, wherein individual carbon atoms are optionally replaced by oxygen atoms or —NRz—,
- Rx are each identical or different and are hydrogen or monovalent, optionally substituted hydrocarbon radicals having 1 to 20 carbon atoms, wherein individual carbon atoms may be replaced by oxygen atoms,
- Rz are each identical or different and are hydrogen or monovalent, optionally substituted hydrocarbon radicals having 1 to 20 carbon atoms, wherein individual carbon atoms may be replaced by oxygen atoms,
- a is 0, 1, 2 or 3,
- b is 0 or 1,
- p is an integer from 1 to 1000,
- q is 0 or an integer from 1 to 100 and
- r is 0 or an integer from 1 to 100,
- with the proviso that a+b is ≤3 and at least one R2 radical is present.
