摘要: A highly filled, ceramic-like thermoplastic polyester resin molding composition, characterized as containing a polyethylene terephthalate base resin, an impact modifier system containing a copolymer and terpolymer, glass fibers, and a mineral filler. Shaped articles prepared from the molding composition exhibit a ceramic appearance and feel, glossy surface finish, improved impact strength, and high specific gravity.

摘要: The instant invention involves a process for preparing carboxylic acid esters which comprises coreacting a carboxylic acid and an aliphatic mono or polyol by maintaining one of the reactants in a reactor at elevated temperatures and adding the other reactant to the reactor over a period of time. By employing this process esterification times are significantly reduced.

摘要: The instant invention involves a process for preparing acrylic acid esters which comprises coreacting an acrylic acid and an aliphatic mono or polyol by maintaining one of the reactants in a reactor at elevated temperatures and adding the other reactant to the reactor over a period of time. By employing this process esterification times are reduced significantly.
摘要翻译: 本发明涉及一种制备丙烯酸酯的方法,该方法包括通过在反应器中将一种反应物保持在升高的温度下并在一段时间内将另一种反应物加入到反应器中来共聚丙烯酸和脂族单或多元醇。 通过使用该方法,酯化时间显着降低。
