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 present invention relates to the forming of amorphous or near-amorphous, ternary films of W-Si-N on substrates by chemical vapor deposition of WF 6 , SiH 4 and NH 3 and a carrier gas. The present invention method will allow the conformal forming of amorphous or near-amorphous, ternary films of W-Si-N on patterned non-planar substrates at temperatures at or below about 450° C., by chemical vapor deposition of WF 6 , SiH 4 and NH 3 and a carrier gas. A typical temperature range for the formation of the films is between 473° K. and 773° K., while the reactor pressure can be varied between 0.1 to 50 Torr. The composition of the deposited films is adjusted by varying the flow ratios of the reactive gases.
