A process for preparing a polymeric Antistatic agent for Polyester and Polyester base units completed.

摘要

Process for the preparation of a polymeric Antistatic Agent on the basis of a Polyester and Polyether units completed the Antistatic Agent comprising at least 75 mol percent of Polyester in units of General formula (i), and between 5 and 25 percent of moles or in The terminated Polyether formula: (- CH2 CH2 - or N - R)Where n is an integer of 8 to 20; and R is a radical of formula (ii), in which x has a value between 12 and 16.consiste in polymerizing the monomers in the presence of a catalyst for Ester exchange with agitation and at elevated temperature
