摘要： PROBLEM TO BE SOLVED: To obtain a specific new polythiol useful as a raw material for plastic lens of high refractive index and high Abbe's number with high heat resistance. SOLUTION: This new compound is a compound of the formula, e.g. 2- mrcaptomethyl-6-mercapto-1,4-dithiacycloheptane. The compound of the formula is obtained by the following process: hydrogen sulfide is reacted with an epihalohydrin to synthesize a bis(3-halogeno-2-hydroxypropyl sulfide, which, in turn, is reacted with thiourea in the presence of a hydrohalogenic acid such as hydrochloric acid or hydrobromic acid to form an isothiuronium salt, which is then hydrolyzed with a base such as ammonia water or an aqueous sodium carbonate solution. Furthermore, the compound of the formula and a polyisocyanate are homogeneously mixed together with an additive or the like followed by defoaming the mixture e.g. under agitation at reduced pressures, and the resultant defoamed liquid is injected into a mold and cure by heating to obtain a urethane-based plastic lens; wherein the above heating is carried out at 0-200 deg.C and the curing is finished in 1-100 h.

摘要： PROBLEM TO BE SOLVED: To obtain a new polyisocyanate capable of producing urethane-based optical materials which can ensure the optical characteristics and toughness of conventional urethane-based plastic lens materials for spectacles, have largely improved heat resistance, and are useful for optical uses except the spectacles. SOLUTION: A compound of formula I, for example, tricyclothiaoctanediisocyanate. The compound of formula I is obtained by reacting a polyamine of formula II or its hydrochloride with phosgene. The compound of formula II is obtained, for example, by reacting norbornanediene as a starting raw material with a sulfur dihalide such as sulfur dichloride to synthesize a tricyclothiaoctane dihalogenide, reacting the dihalogenide with an alkali metal azide compound such as sodium azide preferably at 0 to 150 deg.C to produce tricyclothiaoctanediazide, and then reducing the product, for example, by a method using phosphine and a mineral acid such as hydrochloric acid.

摘要： PROBLEM TO BE SOLVED: To obtain the subject optical material having an improved refractive index and useful as an eye-glass lens, etc., by introducing selenium atom(s) into a molecule of which an optical material is produced. SOLUTION: These optical material and plastic lens can be obtained by subjecting a composition, which contains at least one or more kinds selected from a reactive monomer having at least one or more selenium atoms in a molecule and its oligomer, to cast polymerization. Examples of the monomer or oligomer include a selenium atom-containing active hydrogen compound having at least one or more functional groups selected from hydroxy, mercapto, seleno and amino in a molecule and a selenium atom-containing self- polymerizable compound having at least one or more functional groups selected from (meth)acrylic, allyl carbonate, etc., in a molecule. The plastic lens can be obtained, for example, by mixing 4-thia-1-selenane-2,6-dimercaptomethyl, m-xylylenediisocyanate, dibutyltin dichloride and dioctyl phosphate to obtain a homogeneous solution, and subsequently heating the solution to cure it.
