Actinic radiation activated hydrosilation reaction compsn.

摘要

Compsn. suitable for effecting a hydrosilation addn. process on exposure to actinic radiation comprises (A) an Si cpd. contg. at least one Si-bonded H atom, there being not more than 2H atoms attached to any one Si atom; (B) a cpd. contg. aliphatic (pref. olefinic) unsatn.; and (C) a Pt complex having a UV-displaceable gp., pref. an (eta-diolefin) (sigma-aryl) Pt complex. Cpds. (A) and (B) can be monomeric or polymeric.
