A radiation-sensitive resin composition suitable as a chemically-amplified resist is provided. The composition comprised (A) a resin insoluble or scarcely soluble in alkali, but becoming alkali soluble by the action of an acid, and (B) a photoacid generator. The resin comprises a recurring unit of the following formula (I),

This invention relates to metal complexes which are useful as catalyst components in olefin metathesis reactions, atom or group transfer radical polymerisation or addition reactions and vinylation reactions. It also relates to the direct one-step synthesis of pyrrole, furan and thiophene compounds, such as dialkyl 1H-pyrrol-1-yl methyl phosphonates, from diallyl compounds.
Disclosed is a method for purifying a polymer in which a solution containing a cyclic olefin polymer having at least a repeating structural unit [A] represented by the general formula (1) and a metal component is brought into contact with an organic compound having a basic functional group and an acidic functional group, and then the resulting solution is brought into contact with a basic adsorbent to remove the metal component contained in the solution.
