摘要:The subject invention relates to a technique for synthesizing rubbery non-tapered, random, copolymers of 1,3-butadiene and isoprene. These rubbery copolymers exhibit an excellent combination of properties for utilization in tire sidewall rubber compounds for truck tires. By utilizing these isoprene-butadiene rubbers in tire sidewalls, tires having improved cut growth resistance can be built without sacrificing rolling resistance. Such rubbers can also be employed in tire tread compounds to improve tread wear characteristics and decrease rolling resistance without sacrificing traction characteristics. This invention more specifically discloses a process for the synthesis of isoprene-butadiene rubbers which comprises copolymerizing isoprene monomer and 1,3-butadiene monomer in an organic solvent in the presence of a catalyst system which is made by the sequential steps of (1) mixing (a) an organoaluminum hydride, (b) a member selected from the group consisting of aliphatic alcohols, cycloaliphatic alcohols, aliphatic thiols, cycloaliphatic thiols, trialkyl silanols, and triaryl silanols, and (c) optionally, 1,3-butadiene in an organic solvent to produce a modified organoaluminum catalyst component; (2) adding an organometallic compound which contains a metal from Group III-B of the Periodic System to the modified organoaluminum catalyst component to produce a Group III-B metal containing catalyst component; and (3) adding a compound which contains at least one labile halogen atom to the Group III-B metal containing catalyst component.

摘要:The 2-(4-tolylsulfonyl)ethoxymethyl (TEM) as a new 2'-OH protecting group is reported for the RNA synthesis on the solid support using the phosphoramidite chemistry. The usefulness of the 2'-0-TEM group is exemplified by the synthesis of 12 different oligo-RNAs of various sizes (14-38nt long). The stepwise coupling yield varied from 97 - 99 % with an optimized coupling time of 120s. Synthesis of all four pure phosphoramidite building blocks are also described. Two new reliable parameters, δc2' - δc3s and δn2' - δH3' have been suggested for the characterization of isomeric 2'-0-TEM and 3'-0-TEM as well as other isomeric mono 273 '-protected ribonucleoside derivatives. The most striking feature of this strategy is that the crude RNA prepared using our 2'-0-TEM strategy is sufficiently pure (>90 %) for molecular biology research without any additional purification step, thereby making oligo-RNAs easily available at a relatively low cost, saving both time and lab resources.
