Abstract
The invention deals with the preparation, compositions, and application of certain high molecular weight hydrophobic citrate polyesters of guerbet alcohols and their alkoxylates, which are useful in polycarbonate processing.
Claims10
A polycarbonate resin composition containing an effective mold releasing amount of a guerbet citrate ester mold release agent conforming to the following structure:
- ##STR9## R is selected from;
- ##STR10## or ##STR11## n has a value from 1 to 15;
- m and o independently range from 0 to 5;
- R.sup.1, R.sup.2 and R.sup.3 are independently selected from ##STR12## wherein R.sup.4 and R.sup.5 may be the same or different saturated aliphatic groups;
- EO is ethylene oxide;
- PO is a propylene oxide group;
- x, y and z are independently between 0 and 10, said ethylene oxide being present in block or random manner by optionally premixing the oxides and the total carbon content of the alcohol derived portion of the molecule, in each instance, ranging from about 12 to about 40 carbon atoms.
