摘要:
The object of the present invention is to provide a polycarbonate resin composition which has excellent transparency and durability against molding heat, which gives a molded article having an excellent mold release property, reduced strains, improved cracking resistance and, preferably, weatherability, and which is particularly suitable for a transparent member for a vehicle, pellets thereof and a molded article thereof, and the present invention provides a polycarbonate resin composition obtained by blending 100 parts by weight of a polycarbonate resin (Component A) and 0.005 to 2 parts by weight of a full ester (Component B) from an aliphatic polyhydric alcohol having 4 to 8 hydroxyl groups and 5 to 30 carbon atoms and an aliphatic carboxylic acid having 10 to 22 carbon atoms, said Component B having a 5% weight loss temperature, measured by TGA (thermogravimetric analysis), of 250 to 360° C. and having an acid value of 4 to 20, pellets thereof and a molded article thereof.
摘要:
A polycarbonate resin composition comprising 100 parts by weight of a polycarbonate resin (component A), 0.01 to 10 parts by weight of at least one ultraviolet light absorber (component B) selected from the group of a specific cyclic imino ester, and 0.01 to 1 part by weight of a fatty acid ester compound (component C) which is an ester of a polyhydric alcohol and an aliphatic carboxylic acid and has a molecular weight of 500 to 2,000 g/mol, as well as molded articles thereof. The polycarbonate resin composition provides molded articles having excellent transparency, color and resistance to ultraviolet radiation, is excellent in heat stability at the time of molding and releasability and fully suppresses the production of a deposit on a metal mold.

摘要:
Compounds having a diphenylmethane skeleton are superior in broad utility and stability, and are useful as a protecting reagent (anchor) of amino acid and/or peptide in the liquid phase synthesis and the like of a peptide having a C-terminal etc., which are of a carboxamide(-CONHR)-type, and in organic synthetic reaction methods (particularly peptide liquid phase synthetic methods), and may be contained in a kit for peptide liquid phase synthesis.
摘要:
The present invention provides a particular branched chain-containing aromatic compound. The branched chain-containing aromatic compound of the present invention is easily-soluble in isopropyl acetate superior in liquid-separation operability, and can be used for a production method of peptide and the like, which provides a final product simply by extraction separation, without crystallization and isolation of each intermediate in each step.
摘要:
A polishing pad capable of improving an affinity to polishing liquid and stabilizing polishing performance is provided. A polishing pad 10 is equipped with a urethane sheet 2. The urethane sheet 2 has a polishing surface P for polishing an object to be polished. The urethane sheet 2 is formed by a dry molding method and is formed by slicing a polyurethane foamed body which is obtained by reacting and curing mixed liquid in which an isocyanate-group containing compound, water, a foam control agent and a polyamine compound are mixed. Foams 3 are dispersed approximately uniformly inside the urethane sheet 2. Opened pores 4 which are opened parts of the foams 3 are formed at the polishing surface P. Inside the urethane sheet 2, the foams 3 formed adjacently to each other are communicated by communication holes 9, and the communication holes 9 are formed at a ratio of 800 holes/cm2 or more when observed from a side of the polishing surface P. Polishing liquid moves via the communication holes 9 and the foams 3.
