A polymer containing a recurring unit having an aliphatic polycyclic structure, wherein at least two atoms constituting the ring skeleton of the aliphatic polycyclic structure constitute the main chain of the polymer, and the recurring unit has an aliphatic ring containing a sulfonyl group as the constitutive group of the ring skeleton, has high refractivity, high Abbe's number, high-level heat resistance, high-level light transmittance and low water absorption.

Polymer, method for producing polymer, resin composition for optical material, shaped article, optical material, and lens

An optical part comprising a thermoplastic resin having a recurring unit represented by the following formula (1): wherein R represents a hydrogen atom, an alkyl group, or an aryl group; G represents a divalent linking group; A represents an oxygen atom, a sulfur atom, or &#x2014;N(R)&#x2014;; Rrepresents a hydrogen atom, an alkyl group, or an aryl group; Q represents an atomic group of forming a hetero ring; and l indicates 0 or 1.

Thermoplastic resin, organic-inorganic hybrid composition and optical parts

A heat-resistant cured product is efficiently produced by obtaining a semi-cured product where a curable resin composition containing a (meth)acrylate monomer, a non-conjugated vinylidene group-containing compound and a thermal radical-polymerization initiator is processed by at least one of photoirradiation and heating to give a semi-cured product having a complex viscosity of from 10to 10mPa&#xb7;s at 25&#xb0; C. and at a frequency of 10 Hz; and putting the semi-cured product in a forming die for pressure formation therein, and heating it therein for thermal polymerization to give a cured product.

Semi-cured product, cured product and method of manufacturing these, optical component, curable resin composition

Disclosed is a curable resin composition comprising a polymer (A) that has a main chain comprising carbon atoms and a side chain having a polymerizing unsaturated linking group and has a cyclic structure in the main chain and/or the side chain, and a compound having a polymerizing unsaturated group. The curable resin composition has good optical characteristics, good heat resistance and good moldability.
