ABSTRACT:
Novel organopolysiloxanes having one silanol group within a molecule and the method for manufacturing them at high purity and high yield. The organopolysiloxanes having a silanol group are expressed by the formula (1) below: ##STR1## wherein R.sup.1 is a monovalent hydrocarbon group with 1 to 8 carbon atoms, each of R.sup.2, R.sup.3 and R.sup.4 is a monovalent hydrocarbon group with 1 to 8 carbon atoms or a siloxyl group expressed by --OSiR.sup.5 R.sup.7, wherein R.sup.5, R.sup.6 and R.sup.7 are monovalent hydrocarbon groups with 1 to 8 carbon atoms, Y is either a hydrogen atom, a halogen atom, or a monovalent hydrocarbon group with 1 to 12 carbon atoms, n is an integer of from 0 to 12, and a is either 0 or 1, with the proviso that the grouping Y--(CH.sub.2).sub.n --Si does not includes H--Si, CH.sub.3 --Si or a hydrolyzable silyl group.
