Provided is a chlorinated polyether which has excellent solubility in solvents and excellent thermal stability, has the excellent effect of improving the adhesion of coating materials, inks, and adhesives to polyolefins, can be expected to be usable as a flame retardant, and is useful also as a novel starting material for polyurethanes. The polyether is a novel chlorinated polyether containing, as a repeating unit, at least one of the chlorinated-ether residue represented by the following formula (1) and the chlorinated-ether residue represented by the following formula (2). Also provided is a novel polyurethane obtained therefrom. 

Chlorinated polyether and polyurethane obtained therefrom

Improved nanolithography components, systems, and methods are described herein. The systems and methods generally employ a resistively heated atomic force microscope tip to thermally induce a chemical change in a surface. In addition, certain polymeric compositions are also disclosed.

Thermochemical nanolithography components, systems, and methods

A sulfur-containing cyclic olefin resin comprising a unit represented by the following general formula (1) and having a weight average molecular weight of from 1,000 to 1,000,000. (Here, Rto Reach independently represents a hydrogen atom, an alkyl group having from 1 to 20 carbon atoms, an aralkyl group having from 1 to 20 carbon atoms, an aromatic group having from 1 to 20 carbon atoms, a cyano group, an alkoxy group having from 1 to 10 carbon atoms or a heterocyclic compound, further Rto Rmay be a halogen atom, Rand R, and Rand Rmay form a ring containing carbon, oxygen, sulfur or nitrogen, Rand Reach independently represents a hydrogen atom or a methyl group, . . . represents a single bond or a double bond, and l and m each is 0 or 1.)

Sulfur-containing cyclic olefin resin and its production method

A transition metal compound having a ligand with an azaferrocene structure or a ferrocene structure. The transition metal compound is used in combination with an activating cocatalyst, as a catalyst for polymerization of olefins.

Transition metal compound, coordinative compound, catalyst for polymerization of olefin, and process for polymerization of olefin using the catalyst

Benzyl alcohol of high purity is produced by supplying benzyl acetate, water and acetic acid to a hydrolysis reactor packed with a solid acid catalyst. The liquid reaction mixture produced, which contains benzyl acetate, water, benzyl alcohol and acetic acid, is supplied to an acetic acid-water recovery column, Benzyl alcohol and benzyl acetate are recovered while acetic acid is removed and returned to the hydrolysis reactor.

Process for producing benzyl acetate and benzyl alcohol

The present invention relates to a process for producing benzyl acetate and benzyl alcohol. Benzyl acetate itself is useful as a solvent and a perfume. Benzyl alcohol which is derived from the benzyl acetate by hydrolysis or by transesterification with methanol is an important compound useful as a powerful solvent, a nontoxic medical additive, and an intermediate compound for agricultural chemicals and medicines.

A lactone is prepared by catalytically hydrogenating a dicarboxylic acid having 3 to 10 carbon atoms or a functional derivative thereof in the presence of a catalyst comprising a metal selected from the elements of group VIII of the periodic table or a combination of said metal with an element selected from the elements of groups IVa, VIb and VIIb of the peridic table, and further in the co-presence of an alkali metal salt or an alkali metal hydroxide.

Process for preparing lactones

N-substituted maleimide represented by formula (2): ##STR1## is produced from N-substituted maleamic acid monoester represented by formula (1): ##STR2## in the presence of an acid catalyst by elmination of an alcohol from the monoester. The above N-substituted maleamic acid monoester represented by formula (1) is produced by esterification of N-substituted maleamic acid represented by formula (3): ##STR3## with an alcohol R.sup.2 -OH in the represence of an acid catalyst.
