Procedure for obtaining sepiolite surface esterified with organic acids such as via improving the technological properties of the thermoplastic cos crystalline compounds that contain

摘要

The process for improving the properties of crystalline thermoplastic composites contg. sepiolite consists of treating the sepiolite in benzne suspension at b. pt. with an aliphatic mono-carboxylic acid in presence of a condensn. catalyst, e.g. p-toluene sulphonic acid, for 1-2 hours, followed by filtration, washing and drying in vacuum. It is carried out in a double chamber reactor, through which circulates a heating fluid at 120 deg. C.
