A glassy hyperbranched polymer (HBPG) was synthesized and dispersed within an aeronautical graded epoxy matrix as toughening agent. This filler is a polyester characterized by a Tg higher then room temperature (similar to 90 degrees C) and obtained by means of bulk poly-condensation reaction starting from a diphenolic acid as precursor.

Abstract
A glassy hyperbranched polymer (HBPG) was synthesized and dispersed within an aeronautical graded epoxy matrix as toughening agent. This filler is a polyester characterized by a Tg higher then room temperature (similar to 90 degrees C) and obtained by means of bulk poly-condensation reaction starting from a diphenolic acid as precursor.File in questo prodotto:
