    • The invention provides a process for preparing a polysiloxane-containing resin which comprises copolymerizing a polysiloxane-type macromonomer with a vinyl monomer, characterized in that the polysiloxane-type macromonomer is one prepared by reacting about 70 to about 99.999 mole % of a compound (A) represented by the formula ##STR1## wherein R.sub.1 represents aliphatic hydrocarbon group having 1 to 8 carbon atoms or phenyl group, and R.sub.2, R.sub.3 and R.sub.4 each represent alkoxyl group having 1 to 4 carbon atoms or hydroxyl group with about 30 to about 0.001 mole % of a compound (B) represented by the formula ##STR2## wherein R.sub.5 represents hydrogen atom or methyl group, R.sub.6, R.sub.7 and R.sub.8 each represent hydroxyl group, alkoxyl group having 1 to 4 carbon atoms or aliphatic hydrocarbon group having 1 to 8 carbon atoms with the proviso that R.sub.6, R.sub.7 and R.sub.8 can not be aliphatic hydrocarbon groups having 1 to 8 carbon atoms at the same time, and n is an integer of 1 to 6, the polysiloxane-type macromonomer having at least two free functional groups selected from hydroxyl groups and alkoxyl groups per molecule, and the macromonomer having a number-average molecular weight of about 400 to about 100,000.
