Abstract

Process for preparing hot melt adhesives of the polyester type, characterized in that linear polyesters of terephthalic acid with ethylene glycol are heated to a temperature of 270 to 290º c, until they are hot melted, and then sterolized by addition of ten to forty by mole percent of poly (ethylene isophthalate) whose limiting viscosity index is between 0.2. And 0.5, based on 100 parts of poly (ethylene terephthalate), the low molecular weight products of the sterolysis reaction are then separated from the reaction mixture using reduced pressure, after which the hot melt adhesive the resulting final, which has a limiting viscosity index comprised between 0.2 and 0.5, is introduced into molds in which the adhesive is shaped, by solidification in applicable forms.
