The subsequent tack and adhesion of a silicone pressure-sensitive adhesive can be improved by incorporating into the adhesive a small amount of an organopolysiloxane resin having a majority of R.sub.3 SiO.sub.1/2 siloxane units and the balance (R.sup.2 O).sub.a SiO.sub.(4-a)/2, preferably SiO.sub.4/2, siloxane units. The resulting composition, when brought into contact with a release liner, such a peelable protective sheet or the backside of the next turn in a roll of tape, have better tack and/or adhesion when separated from that liner than an analogous composition which does not contain the resin.

The present invention relates to a method for the preparation of tertiary-hydrocarbylsilyl compounds through a Grignard reaction. A Grignard reagent of formula RMgX, in which R is a tertiary-hydrocarbyl group and X is a halogen atom, is reacted with a silicon compound of formula R.sup.1.sub.a SiX.sub.4-a ; where R.sup.1 is a substituted or unsubstituted monovalent hydrocarbon group and a is an integer with a value of zero to three. The process is ran in the presence of a catalytic quantity of a cyano compound or a thiocyanate compound.
