Abstract
Procedure for preparing low viscosity unsaturated polyester resins. Maleic anhydroid, maleic acid, smoke acid or a mixture of them in association with isoftalic acid; together with one or more glycoles. Such polycondensation is performed in an atmosphere of inert gas and at temperatures comprised between 150 and 260ºc and leads to the obtaining of a rent, which is subsequently cooled and dissolved in a copomimerizable monomer with it. Preferably stirene or vinyl toluene is used as a monomer, by a percentage in weight with respect to the total of 25 to 40 per 100. The resins obtained are conformable and of employment in the obtaining of various products, optionally reinforced with glass fiber. (Machine-translation by Google Translate, not legally binding)
