Methods for in situ formation of high glass transition temperature polymers

The method of treating a subterranean formation penetrated by a wellbore, comprising:

• lowering a wellbore tool into the subterranean formation, wherein the tool comprises a first partition containing a polymerizable composition comprising a polycyclic monomer and a benzoate ester, and a second partition containing a ring opening metathesis catalyst;
• releasing the polymerizable composition from the first partition;
• releasing the ring opening metathesis catalyst from the second partition;
• contacting the polymerizable composition and the ring opening metathesis catalyst in a mixing region located below a surface of the earth, wherein the polymerizable composition and the ring opening metathesis catalyst are maintained separate from one another until the polymerizable composition and the ring opening metathesis catalyst are contacted within the mixing region located below the surface of the earth;
• and
• reacting the polymerizable composition and the ring opening metathesis catalyst in situ to form a polymer, wherein the polymerizable composition comprises 0.5 vol % to 20 vol % of a benzoate ester.
