摘要:
A macromolecular material composition which comprises a macromolecular material and a modifier which comprises a polyvinyl cyclohexane compound having hydroindane structure. The modifier improves melt flow characteristics, flexibility at a low temperature, and mechanical characteristics, such as bending modulus and bending strength, of the material, and do not bleed or give bad smell.

摘要:
Methacrylate esters of alcohols having an ether linkage and/or an alicyclic ring can be obtained with no trouble of coloration or polymer formation during the production and for the product. An alcohol having an ether linkage and/or an alicyclic ring is treated with an alkaline substance, and the treated alcohol is caused to react with methyl methacrylate for a transesterification reaction in the presence of an alkaline substance.
摘要:
An amino compound of formula (I): wherein R₁, R₂, R₃, R₄, R₅, R₆, R₇ and R₈ are independently -H, -CH₂OH or -CH₂OCH₃, with the proviso that not all of R₁ through R₈ are simultaneously hydrogen.
摘要:
An epoxy resin composition comprising (A) an epoxy resin, (B) an alicyclic or aromatic polycarboxylic acid anhydride, (C) 4-ketopimelic acid dilactone, and if necessary (D) a hardening accelerator can give a cured article having excellent properties such as elongation, flexibility, hardness, tensile strength, etc.
摘要:
A lactone of the formula: wherein R, through R 8 are independently hydrogen or C 1-5 alkyl, obtained by decarboxylation condensation reaction of a saturated alicyclic 1,2-dicarboxylic acid anhydride, is a good curing agent for thermosetting resins.
