Abstract:
1. Polyester-polysiloxane copolymers characterized in that a trimethylcaprolactone is used for building up the polyester block and are compounds of the general formula (I) where M=(R M′=(R M″=(R D=(R D′=(R D″=(R T=(R Q=(SiO where a=0 to 10, b=0 to 15, c=0 to 350, d=0 to 50, e=0 to 100, f=0 to 12, g=0 to 8, with the proviso that b+e≧1 where R R and R where C=independently of the others, identical or different polyester radicals of the formula (IV) B=independently of the others, identical or different divalent heteroatom groups; A=independently of the others and identical or different, a (k+1)-valent organic radical; C′=independently of the others, identical or different polyester radicals of the formula (V) B′=independently of the others, identical or different divalent radicals containing carbonyl groups, where X=independently of the others and identical or different, O or NH, preferably oxygen O, R R R R and h=0 to 22, i=0 to 50, j=0 to 50, k=1 to 3, l=0 to 50, m=0 to 50, n, o, s, t=0 to 50, p, u=1 to 4, q, v=0 to 50, with the proviso that n+o≧2 or s+t≧2.
