Abstract:
A process for making silyl endblocked organic polymers of the formula R.sup.1.sub.3 SiM said process comprising contacting under anhydrous conditions, components comprising a reagent selected from the group consisting of M' monomers, oligomers of M' and mixtures thereof, with a silyl cation R.sup.1.sub.3 Si.sup.+ whereineach R.sup.1 is independently selected from the group consisting of unsubstituted hydrocarbons, unsubstituted hydrocarbonoxy groups, hydrogen, halogens and monovalent siloxane-free silicon-containing groups,M' is an ethylenically unsaturated monomer having the formula H(R.sup.3)--C.dbd.C--(R.sup.2).sub.2,each R.sup.2 is independently selected from the group consisting of unsubstituted hydrocarbons, substituted hydrocarbons, hydrogen and halogens,R.sup.3 is selected from the group consisting of hydrogen and a methyl group andM is an organic polymer made by the addition polymerisation of M'.
