ABSTRACT:
An MQ organopolysiloxane compatible with organic plastics, has an epoxy-containing organic group, and has the following general formula ##STR1## R.sup.1 represents monovalent hydrocarbon groups, R.sup.2 represents the hydrogen atom and monovalent hydrocarbon groups, R.sup.3 represents epoxy-containing organic groups and alkoxysilylalkyl groups, a is 0 or a positive number, b and c are positive numbers, a/c has a value of 0 to 4, b/c has a value of 0.05 to 4, and (a+b)/c has a value of 0.2 to 4. Also, a method for the preparation of this organopolysiloxane comprises an addition reaction of an Si-H containing organopolysiloxane with an epoxy-containing compound in the presence of a hydrosilylation catalyst.
