摘要:
A process for preparing an epoxidized organic polymer by dispersing or suspending a solid organic polymer in an organic solvent and epoxidizing the dispersed or suspended polymer with a peroxide. The epoxidized polymer thus obtained is usable for coating materials, resin modifiers, rubber modifiers or adhesives, thus being extremely useful. The epoxidized organic polymer is useful to prepare a thermoplastic resin composition having improved mechanical strength, and comprising a thermoplastic resin, an epoxidized EPDM and an acid anhydride. The thermoplastic composition can be used to prepare a primer composition including a 100 parts by weight of an epoxidized EPDM and 50 to 70 parts by weight of a product of chlorination of a polyolefin modified with an unsaturated carboxylic acid or an anhydride thereof. An unvulcanized rubber composition can be prepared for the epoxidized EPDM, a diene polymer and a vulcanizing agent, and the unvulcanized rubber composition can be used in a process for producing rubber moldings by extruding the unvulcanized rubber composition and vulcanizing the extrudate.

To provide the mechanical brake actuator enabling to downsize the device and to reduce the manufacturing costs of the parts. The mechanical brake actuator comprises the strut (23) which engages with one brake shoe (12) and has two facing plates (23b) with a strut-bridge (23a) connecting therebetween and the plate-like brake lever (24) which engages with the other brake shoe (13). The brake lever (24) is retained in the space (23c) between the facing strut plates and is pivotally supported on the strut (23), and the inner cable (41) of the brake cable (40) connected to the free end (24e) of the brake lever (24) via the connecting pin (43). The mechanical brake actuator which is operated by pulling the inner cable (41) comprises the clip (70), which rotatably attaches to the strut-bridge (23a) and restricts the rotation of the brake lever (24) in the cable releasing direction.
摘要:
A liquid thermosetting epoxy resin composition contains a base resin in combination with a curing agent and a curing accelerator or with a curing catalyst. The base resin includes a cycloaliphatic epoxy compound having at least one alicyclic skeleton and two or more epoxy groups per molecule, and a polyol oligomer having two or more terminal hydroxyl groups. An optical semiconductor device includes an optical semiconductor element sealed by using the liquid thermosetting epoxy resin composition. The composition yields a cured resinous product which is free from curing failure, is optically homogenous, has a low elastic modulus in bending, a high bending strength, a high glass transition temperature, a high optical transparency and is useful for optical semiconductors.

摘要:
A high-purity cycloaliphatic diepoxy compound of General Formula (II) is an epoxidized product of a cycloaliphatic diolefinic compound of General Formula (I) having an isomer content as detected in gas chromatography (GC) of 15% or less: wherein X represents a bivalent group selected from the group consisting of, for example, O, S, —SO—, —SO2—, —CH2—, and —C(CH3)2—; and R1 to R18 may be the same as or different from each other and each represent hydrogen atom, a halogen atom, a hydrocarbon group which may contain oxygen atom or a halogen atom, or an alkoxy group which may be substituted. Such a high-purity cycloaliphatic diepoxy compound is prepared by producing the cycloaliphatic diolefinic compound through distillation, epoxidizing the compound with an aliphatic percarboxylic acid containing substantially no water, carrying out desolvation, and further purifying the epoxidized compound through distillation.
