ABSTRACT:
A polydimethylsiloxane compound terminated at one end by a branched aminoalkyl group, having the average formula ##STR1## wherein R.sup.1 and R.sup.4 are monovalent hydrocarbon groups having 1 to 20 carbon atoms, R.sup.2 and R.sup.3 are alkylene groups having at least two carbon atoms, Me is a methyl radical, m is an integer between 6 and 1,000 and n is an integer between zero and 6, is disclosed. The polydimethylsiloxane of the invention can be easily prepared by the method described and imparts improved surface properties, such as water repellency and slipperiness, to organic resins modified therewith.
