摘要:By utilizing the vapor phase polymerization techniques of the present invention, numerous distinct and highly beneficial advantages are realized. For instance, cis-1,4-polyisoprene rubber and high cis-1,4-polybutadiene rubber having a consistent and controllable molecular weight can be easily and practically prepared without utilizing a solvent. The subject invention more specifically discloses a method for vapor phase polymerizing isoprene into cis-1,4-polyisoprene in a process comprising the steps of: (1) charging into a reaction zone said isoprene and a preformed catalyst system which is made by reacting an organoaluminum compound with titanium tetrachloride, preferably in the presence of at least one ether; wherein the isoprene is maintained in the vapor phase in said reaction zone by a suitable combination of temperature and pressure; (2) allowing said isoprene to polymerize into cis-1,4-polyisoprene at a temperature within the range of about 35 DEG C. to about 70 DEG C.; and (3) withdrawing said cis-1,4-polyisoprene from said reaction zone. It has been determined that gel formation can be reduced by conducting the polymerization of isoprene monomer in the presence of a diarylamine, such as para-styrenated diphenylamine.

标 题:Synthesis of 1,4-polybutadiene
发明人：RACHITA MICHAEL JOSEPH; JOHNSON SCOTT EDWARDS

摘要:This invention is based upon the unexpected discovery that alkylated diphenylamines can be used in conjunction with nickel based catalyst systems which contain (a) an organonickel compound, (b) an organoaluminum compound, and (c) a fluorine containing compound to produce cis-1,4-polybutadiene having reduced molecular weight and an increased level of branching. This results in the cis-1,4-polybutadiene exhibiting good processability without sacrificing cold flow characteristics. Additionally, the alkylated diphenylamine which remains in the rubber acts in a manner which provides it with antioxidant protection. In other words, the use of alkylated diphenylamines accomplishes the three major objectives that are realized by employing para-styrenated diphenylamines (reduced molecular weight, regulated polymer macrostructure through branching and antidegradant protection). However, the utilization of alkylated diphenylamines, unlike para-styrenated diphenylamines, offers the additional advantage of being soluble in aliphatic solvents. By virtue of this increased level of solubility in aliphatic solvents, such as hexane, alkylated diphenylamines can be employed at greatly reduced levels of aromatic solvents. Likewise, when mixed catalyst streams containing alkylated diphenyl amines are combined precipitation is minimized compared to para-styrenated diphenylamine significantly improving issues related to fouling. The subject invention more specifically discloses a process for producing cis-1,4-polybutadiene having a reduced molecular weight and improved processability which comprises polymerizing 1,3-butadiene in the presence of (a) an organonickel compound, (b) an organoaluminum compound, (c) a fluorine containing compound, and (d) an alkylated diphenylamine; wherein the alkylated diphenylamine has alkyl groups that contain from 2 to 18 carbon atoms, and wherein the organoaluminum compound and the fluorine containing compound are brought together in the presence of the alkylated diphenylamine.

摘要:Methods of synthesizing platinum-nickel-alloy nanoparticles and supported catalysts comprising the nanoparticles are provided. The methods may comprise forming a reaction mixture in a reaction vessel; heating the reaction mixture sealed in the reaction vessel to a reaction temperature; maintaining the temperature of the reaction vessel for a period of time; cooling the reaction vessel; and removing platinum-alloy nanoparticles from the reaction vessel. The reaction mixture may comprise a platinum precursor, a nickel precursor, a formamide reducing solvent, and optionally a cobalt precursor. In some embodiments the reaction temperature is at or below the boiling point of the formamide reducing solvent, such as from about 120° C. to about 150° C., for example. The platinum-alloy nanoparticles provide favorable electrocatalytic activity when supported on a catalyst support material.
