摘要： This invention provides a catalyst and a process for the hydrogenation of conjugated diolefin polymers which first involves the polymerization or copolymerization of such monomers with an organo alkali metal polymerization initiator in a suitable solvent thereby creating a living polymer. The living polymer can be terminated by the addition of hydrogen. Finally, selective hydrogenation of the unsaturable double bonds in the conjugated diolefin units of the terminated polymer is carried out in the presence of an initiator and at least one rare earth compound of the formula*Cp.sub. MRwhere *Cp is pentamethylcyclopentadiene, M is a rare earth element and R is alkyl, aryl, aralkyl or hydrogen.

摘要： A lightweight absorbent foam is produced using a high internal phase emulsion (HIPE), the production of which incorporates the use of capillary viscosity measurements as an in-line diagnostic for HIPE quality. The in-line diagnostics yield measurements of viscosity slope and amplitude. These measurements offer several advantages for monitoring emulsion quality, including stable high resolution measurement of hardware-independent parameters of the whole flow, without the need for sampling.

摘要： In a process for the preparation of a low density porous crosslinked polymeric material by polymerizing a water-in-oil high internal phase emulsion, curing time of the monomers in the emulsion can be reduced without adversely affecting polymer properties by first advancing one or more of the monomers. All or a portion of the monomers are advanced in the presence of an advancement initiator or a free-radical-producing radiation source for about 5% to about 95% of the time effective to form a solid. Then, a water-in-oil high internal phase emulsion is formed with the advanced monomers and optionally additional monomers or the advanced monomers are added to a water-in-oil high internal phase emulsion containing other monomers. The emulsions containing the advanced monomers are cured. The process provides an improved method to incorporate volatile monomers in the porous polymeric material. The curing time is further reduced by carrying out the polymerization and crosslinking in the presence of a alkylperoxycarbonate or a alkylperoxycarboxylate polymerization initiator that is branched at the 1-position and/or the .alpha.-position.
