摘要： A magnesium halide salt of a 2-alkyl-2-adamantanol is reacted with a carboxylic acid halide such as acrylic chloride or the like in the presence of a tertiary amine to produce a 2-alkyl-2-adamantyl ester (the first invention).
A 2-alkyl-2-adamantanol is reacted with a carboxylic acid such as acrylic acid or the like in the presence of an acid catalyst such as concentrated sulfuric acid or the like and a drying agent composed of an acidic or neutral inorganic compound (e.g. magnesium sulfate) which is a solid at ordinary temperature in a dried state or of a water-absorbing high-molecular compound, to produce a 2-alkyl-2-admantyl ester (the second invention).
The above ester is important as a raw material for a resist for semiconductor production.-

摘要： A membrane sensitive to anions is obtained by forming into a membrane either a composition comprising an onium salt compound such as trioctylmethylammonium chloride or tetraoctylammonium bromide, and an aromatic boric diester compound such as (p-alkyloxy)phenyl borate, or a composition which comprises these two ingredients and a membrane-forming polymer such as polyvinyl chloride or polystyrene, and may further contain a fat-soluble anion salt such as tetraphenyl borate. This membrane can yield an ion-selective electrode which permits hydrogencarbonate ions contained in body fluids to be rapidly determined with high sensitivity and high selectivity and which has a long life.

摘要： The present invention provides an optical composition from which an optical article having reduced poor appearance such as cloudiness and optical strain during lens base material production can be obtained, and when a photochromic compound is added, a photochromic cured body having excellent photochromism and mechanical strength can also be formed, and a polyrotaxane used therefor. The polyrotaxane has a composite molecular structure formed of an axle molecule and a plurality of cyclic molecules clathrating the axle molecule, satisfying at least one of (X) and (Y). (X): A side chain having a secondary or tertiary hydroxyl group is introduced into at least part of the cyclic molecule of the polyrotaxane. (Y): A side chain having a group represented by -A (A is an organic group, and contains at least one hydroxyl group) is introduced into at least part of the cyclic molecule of the polyrotaxane, and a pKa of the hydroxyl group of the compound represented by H-A is 6 or more and less than 14.

摘要： To provide a primer composition for optical articles which comprises (A) a polyrotaxane and (B) a resin and/or precursor thereof. This primer composition for optical articles can suppress the production of a crack in a photochromic coat layer, form a laminate structure that the photochromic coat layer is hardly scratched, and provide a primer coat layer which exhibits excellent adhesion and photochromic properties on an optical substrate.
