Abstract
LA POLIMERIZACION DE ETERES CICLICOS SE LLEVA A CABO UTILIZANDO BIEN ZEOLITAS QUE CONTIENEN CIERTOS CATIONES METALICOS O BIEN PERFLUOROALQUILSULFONATOS DE METALES SELECCIONADOS QUE SE ACOPLAN A SOPORTES SOLIDOS, COMO CATALIZADORES, EN PRESENCIA DE ACELERADORES SELECCIONADOS. LOS POLIETERES PRODUCIDOS SON UTILES COMO MONOMEROS, FLOCULANTES, LUBRICANTES, ETC. LOS POLITETRAHIDROFURANOS SE DESPOLIMERIZAN A TEMPERATURAS ELEVADAS EN TETRAHIDROFURANOS MEDIANTE LA UTILIZACION DE PERFLUOROALQUILSULFONATOS DE METALES SELECCIONADOS QUE SE ACOPLAN A SOPORTES SOLIDOS COMO CATALIZADORES.
