摘要:The Acetal Formation Of Thioketones With Several Diols And Phenols Through Metal Ion-Mediated Desulfurization-Condensation Was Investigated. The Reactivities Of 4,4'-Bis(Dimethylamino)Thiobenzophenone,''Thio-Michler'S Ketone'' (Tmk) And Xanthene-9-Thione (Xt) Toward Alpha,Omega-Alkanediols [ho(Ch2)Noh,N = 2 Similar To 4] In The Presence Of Silver Trifluoroacetate And Triethylamine Were Compared. The Reaction Of Tmk With Glycerol,Trans-And Cis-1,2-Cyclohexanediols,Alpha,Alpha'-Dihydroxy-O-Xylene And Biphenyl-2,2-Diol In The Presence Of Silver Salt Gave The Corresponding Acetals In Good Yields. On The Other Hand,Copper(I) Chloride,In Place Of Silver(I) Salt,Was Useful For Catechol And Pyrogallol To Give Their Acetals,Respectively. It Was Thus Found That Thioketones Are New And Versatile Acetalizing Reagents For Diols And Phenols.

摘要:Process for the synthesis of alpha -chlorinated chloroformates, and new alpha -chlorinated chloroformates. The invention relates to a new process for the manufacture of alpha -chlorinated chloroformates and, to new alpha -chlorinated chloroformates as new industrial products. The process according to the invention consists of a synthesis, by catalytic phosgenation, of alpha -chlorinated chloroformates of the formula: in which: R represents a substituted or unsubstituted hydrocarbon radical and m represents an integer superior or equal to one, this synthesis consisting in reacting phosgene with the aldehyde R-CHO)m, in the presence of a catalyst which is an organic or inorganic substance which is capable in a medium containing an aldehyde of the formula R-CHO)m, phosgene and, possibly, a solvent, of generating a pair of ions one of which is an halogenide anion and the other is a cation which is sufficiently separated from said halogenide anion so as to give to the latter a nucleophilic power enabling it to react with the function(s) aldehyde of the molecule R-CHO)m.

摘要:Herein, we describe polymerized ionic liquids, demonstrate the synthesis of polymerized ionic liquids, and demonstrate the polymerization of triazolium monomers. One embodiment shows the polymeriazation of the triazolium monomers with bis(trifluoromethanesulfonyl)imide anions. In another embodiment we show the feasibility of copolymerizing with commodity monomers such as styrene using free radical polymerization techniques.

摘要:In particular, the invention relates to the synthesis of radiation-curable polyurethane/oligomeric urethane dispersions of anionic and cationic characters, containing neutralization techniques characterized by the selection of counter ions as monomers and/or agents which can be polymers acting as promoters under radiation, to a radiation polyurethane/oligomeric urethane synthesis method that enables the creation of radiation curable binder systems without using cosolvents, surfactants, emulsifiers, defoamers, stabilizers and additives, wherein all components of the radiation-curable binder systems can be polymerized.

标题:Initiator compositions and methods for their synthesis and use
发明人：CRIVELLO JAMES V
摘要:Cationic polymerization initiators of formula ##STR1## are disclosed. The acyl sulfonium salts of the present invention differ from known acyl sulfonium initiators in that the substituents R 2 and R 3 on the sulfur are larger and more complex than the lower alkyl and lower alkylene of known photoinitiators. Processes for the synthesis of the novel acyl sulfonium salts and prepolymer compositions containing them are also disclosed.

摘要:It is important for rubbery polymers that are used in tires, hoses, power transmission belts and other industrial products to have good compatibility with fillers, such as carbon black, silica, clay (including organoclays), and mixtures thereof. To attain improved interaction with fillers such rubbery polymers can be functionalized with various compounds, such as amines. The present invention discloses a process for synthesizing a rubbery polymer that is functionalized to attain improved compatibility with fillers. The present invention more specifically disclosed a process for synthesizing a rubbery polymer that comprises (1) continuously charging (a) a conjugated diolefin monomer, (b) an organolithium compound, and (c) an amine compound into a polymerization zone, wherein the amine compound is selected from the group consisting of alkyl, dialkyl, cycloalkyl or dicycloalkyl amine compounds of the general formula:wherein R represents an alkyl group, a cycloalkyl group, or an alkaryl group containing from 1 to about 12 carbon atoms, and cyclic amine compounds of the general formula:wherein R2 represents a divalent alkylene, bicycloalkane, substituted alkylene, oxy- or N-alkylamino-alkylene group containing from about 3 to about 16 methylene groups; (2) allowing the conjugated diolefin monomer to polymerize in the polymerization zone to produce the rubbery polymer; and (3) continuously withdrawing the rubbery polymer from the polymerization zone.

标 题:Synthesis of multiblock polymers using group IIA and IIB metal cyclic organometallic initiators
发明人：HALL JAMES E
权利人:BRIDGESTONE CORP
摘要:The invention is a practical process for anionically synthesizing multiblock polymers containing a plurality of blocks formed from polar and/or non-polar monomers by using a cyclic organometallic compound initiator that comprises a divalent metal atom and an organic moiety contained in a ring, preferably a cycloorganomagnesium initiator. Activation of the ring metallic atom results in anionic polymerization of the monomers by addition into the initiator ring at the bonds between the metallic atom and its two adjacent carbon atoms, the metallic atom acting as a bridge between the two living ends of the propagating chain. The active chain ends can be coupled or terminated.
