ABSTRACT:
A process for making silyl endblocked organic polymers of the formula R.sup.1.sub.3 SiM is disclosed which comprises contacting under anhydrous conditions M' monomers and/or oligomers of M' with a silyl cation R.sup.1.sub.3 Si.sup.+ devoid of any siloxane bonds wherein each R.sup.1 independently denotes an optionally substituted hydrocarbon or hydrocarbonoxy group, hydrogen, a halogen or a monovalent siloxane-free silicon-containing group and M is an organic polymer made by the addition polymerisation of ethylenically unsaturated monomers M' of the formula H(R.sup.3)--C.dbd.C--(R.sup.2).sub.2 wherein each R.sup.2 independently denotes an optionally substituted hydrocarbon, hydrogen or a halogen and R.sup.3 denotes a hydrogen or methyl group. Preferably the monomer M' is an olefin.
