摘要:
The invention is concerned with silicone copolymer containing terminal and/or pendant oxyalkylene styrene groups which are crosslinkable in the presence of a photoinitiator when exposed to UV radiation and their use in a compositions for coating substrates to provide substrates with anti-adhesive properties.

The invention concerns an organometallic telomer which can be used in particular as biocidal agent.It is represented by the formula: ##STR1## in which: n and p represent numbers between 1 and 100 such that the ratio n/(n+p) is less than or equal to 0.75;R.sub.1 and R.sub.2 which are identical or different represent a hydrogen atom or a methyl group;R.sub.3 represents a linear or branched alkyl group having 1 to 12 carbon atoms, or a substituted or unsubstituted phenyl group;R.sub.4 represents a hydrogen atom or has one of the meanings indicated for R.sub.3 ;M and Y coming from a transfer agent in which Y represents hydrogen, chlorine or bromine and M an electro-attractive organic use.Used for the control of parasitic and in particular marine organisms.
