    Abstract: Polymerizable, mouldable compositions comprise (1) 2-80 parts by weight of a butadiene polymer containing polymerizable ethylenically unsaturated groups and (2) 100 parts by weight of a liquid organic monomer containing polymerizable ethylenically unsaturated groups, at least 75% by weight of component (2) being the acrylic acid ester of tricyclo - [5,2,1,02,6]-decene - (3) - ol - (9). Component (1) may be butadiene homopolymer, particularly the 1,4-polymer; or a copolymer of butadiene with, for example, styrene, a -methyl-styrene, N-vinyl-pyridine and/or acrylonitrile, particularly a copolymer in which the butadiene units are 1,2-linked. Additional monomers which may be included in component (2) can be, for example, those mentioned above in the butadiene copolymers. The compositions may include a polymerization inhibitor, e.g. t-butylhydroquinone or t-butylpyrocatechol; a filler or reinforcing agent, e.g. a glass fibre mat; a pigment; a flame retardant, e.g. a chloroparaffin and tri-(b -chloroethyl) phosphate (stabilized with an epoxidized monoester of glycerol and versatic acid). The compositions are moulded and polymerized in the presence of an initiator such as cyclohexanone peroxide or benzoyl peroxide in combination with a metal salt, e.g. cobalt naphthenate or amine, e.g. dimethylaniline, accelerator.ALSO:The acrylic acid ester of tricyclo-[5,2,1,02,6]-decene -(3)-ol-(9) is prepared by reacting excess acrylic acid with dicyclopentadiene in the presence of BF3 and hydroquinone, firstly at 40 DEG C. and subsequently at 65 DEG C. After removal of the excess acid, washing and extracting, the ester product is distilled in vacuo in the presence of phenothiazine.

    Abstract: A process for consolidating subterranean rock formations comprises injecting under pressure into the formation a liquid material which is curable by polymerization and curing the material by the action of a polymerization catalyst, said liquid material consisting of, or containing as the main component, tri-cyclo-[5,2,1,02,6] -decene-(3)-ol-(9)-acrylate. The liquid material may include other unsaturated monomers, unsaturated polyester resins, and preformed polymers, derived for example from vinyl chloride, butadiene, styrene, acrylic and methacrylic esters, and acrylonitrile. The material may also include a polymerization inhibitor to prevent premature curing. Catalysts exemplified are cyclohexanone peroxide/cobalt naphthenate and benzoyl peroxide/N-methyl-N-b -hydroxypropylaniline. In examples, the cycloaliphatic acrylate is combined with (1) an unsaturated polyester prepared from maleic anhydride, phthalic anhydride and propanediol, (2) polyvinyl chloride and (3) polybutadiene.ALSO:Tricyclo[5,2,1,02,6] - decene - (3) - ol - (9) acrylate (TDA) is prepared by cooling a mixture of hydroquinone, acrylic acid, boron trifluoride and added dicyclopentadiene to 40 DEG C., allowing the temperature to rise to 65 DEG C. over 4 hours. The excess acrylic acid is vacuum distilled and the residue dissolved in pentane, washed with water, 10% Na2CO3 and 5% NaOH solutions. The pentane is distilled off from the organic layer, phenothiazine is added and TDA distilled off under vacuum.
