Functionalized silicone polymers incorporating segments formed from medium-chain fatty acids are generally disclosed herein. Methods of using such compounds, for example, as surfactants, are also disclosed herein, as well as methods of making such compounds, for example, from medium-chain fatty acids derived from natural oils.

A silicone-modified polybenzoxazole resin comprising repeating units of formulae (1a) and (1b) is prepared by addition polymerization. R.sup.1 to R.sup.4 are a C.sub.1-C.sub.8 monovalent hydrocarbon group, m and n are integers of 0-300, R.sup.5 is C.sub.1-C.sub.8 alkylene or phenylene, a and b are positive numbers of less than 1, a+b=1, and X.sup.1 is a divalent linker of formula (2). The resin is flexible, soluble in organic solvents, and easy to use. ##STR00001##

A temporary high-temperature-resistant dispersing agent, and a preparation and a use method thereof. The temporary high-temperature-resistant dispersing agent is a block high-molecular polymer prepared by a one-step reaction from polysiloxane containing an amino group. The prepared block high-molecular polymer may be directly used as a dispersant; the block high-molecular polymer may also be used as a basic formula and used as the dispersant after other auxiliary compositions are added; and the block high-molecular polymer may also be used in combination with one or more other dispersion auxiliaries and/or surfactants to meet dispersion requirements in various special occasions.
