Abstract
Abstract A dispersion is provided for incorporation with a synthetic fiber-forming polymer. The dispersion comprises a polymer additive, such as titanium dioxide, and a glyceride which is non-resin forming when exposed to certain temperatures and pressures for specified time periods and which has an average molecular weight of between about 600 and 2400.
