  An anaerobic liquid acrylate sealant composition contains short portions of one or more types of fibre, particularly aramid fibre pulp, as a filler. A particulate filler such as fumed silica and/or micronized polyethylene may also be present. The composition suitably is based on a high proportion of monofunctional acrylate ester monomer, a low proportion of polyfunctional acrylate ester monomer, and a polyacrylate plasticiser. The composition is used for sealing joints in pipework where it is desired to seal the joint almost immediately but to allow adjustment of the joint for at least 24 hours.

  A method of forming a gasket in situ between two components which comprises injecting into a groove in at least one of said components a curable composition comprising: one or more free-radical polymerizable vinyl esters, and ingredients of a rapid free-radical cure system therefor, the cure system being inactivated prior to injection of the composition, and the composition having a viscosity at 25oC in the range from 200 to 500,000 mPas; and permitting the composition to cure. The composition can be a two part composition wherein the first part contains a prepolymer, monomer and activator and the second part a prepolymer, monomer and activator. The composition can also comprise two expansion reactants, each in a separate part of the composition prior to injection, which react to form a gas in situ in the composition. The gasketing composition is suitable for use in engines and other machines e.g. in industrial manufacturing plants.

  Modified rubber compositions comprise by weight about 15-60% of a highly saturated aliphatic rubber such as ethylene-propylene-diene rubber, about 25-80% of acrylate monomer units; and less than about out 5% multi-functional monomer units. The compositions exist as amorphous heterogeneously dispersed phases. The first phase comprises the copolymer rubber to which polymers of at least 10%, preferably 20%, and more preferably 30% of the other monomer units are grafted. The second phase comprises the other monomers polymerized as homo and copolymers, not grafted to the rubber. Optionally, up to 20% of the composition comprises high index monomer units, e.g., those providing phenyl groups (preferably styrene) having an index of refraction greater than that off the rubber, preferably greater than that of polyacrylate. The high index monomer units may be copolymerized with the acrylate and grafted to the rubber. Greater than 10% and preferably 20% of the monomer units other than rubber are grafted to the rubber. The number average molecular weight of the grafts is between 10,000 and 80,000 daltons. bout 2-20% by weight of one or more polymers may be provided to adjust the refractive indices of the rubber or the polyacrylate phase in the final product such that when the composition is present at the 10% rubber level, the haze can be reduced to less than 20%., Examples for modifying the refractive index of the rubber phase, other than those grafted to the rubber, are block copolymers comprising at least one block providing high index monomer units (preferably styrene) having a higher refractive index than rubber, preferably higher than polyacrylate and at least one block of a saturated aliphatic polymer compatible with the rubber, such as hydrogenated polyisoprene., Other polymers compatible with the polyacrylate phase and having a lower index of refraction than that of polyacrylate, preferably less than the rubber such as those providing vinylidene fluoride monomer units may be utilized. The compositions may be stored and transported to the place of manufacture of polyacrylate products and there incorporated into polyacrylate products to form up to about 80% by weight of said products having high strength and if desired, high clarity.
