A amine mixture of the general formula:
- ##STR7## wherein:
- R represents an initiator radical based on a compound containing Zerewitinoff active hydrogen atoms;
- H represents a hydroxy-containing group of the formula:
- ##STR8## P represents a primary amine-containing group of the formula:
- ##STR9## S represents a secondary amine-containing group of the formula:
- ##STR10## T represents a tertiary amine-containing group of the formula:
- ##STR11## a is 0 to 175;
- b is 0 to 175;
- c is 0 to 30;
- n is 1 to 3;
- the sum a+b+c must be greater than or equal to 2 when n equals 1;
- R' is an alkyl group containing from two carbon atoms to eighteen carbon atoms;
- R" is hydrogen or an alkyl group containing up to eighteen carbon atoms;
- R'" and R"" are independently alkyl groups containing from two to twelve carbon atoms;
- h is from 0 to 0.7;
