An energy sensitive composition comprising a monomeric organometallic complex essentially free of nucleophilic groups and which upon exposure to energy, bonds to basic reactive sites on a substrate via the metal center, leaving the polymerizable group of the complex unreacted and unrestricted; an energy sensitive composition at least one energy sensitive organometallic group is incorporated in or appended to the backbone of a polymer such that the, resulting coordinatively unsaturated organometallic group or groups bond to basic reactive sites on a substrate thus forming, permanent bonds, and further the adherent compositions are useful in applications such as adhesion of polymers to …

Why it's free to use
- Filed May 21, 1992. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended May 21, 2012.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 21, 2014.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
