Unsaturated polyester resin properties

In organic chemistry, an ester is formed as the condensation product of a carboxylic acid and an alcohol, with water formed as the condensate by-product. An ester can also be produced with an acyl halide and an alcohol, in which case the condensate by-product is a hydrogen halide. Polyesters are a category of polymers in which ester functionality repeats withi… WebFeb 28, 2024 · Unsaturated polyesters are macromolecules (molecular weight between 1000 to 3000 gr/mol). These polyesters are produced through a condensation reaction between alcohols and dicarboxylic or polycarboxylic acids. Some dicarboxylic acids contain unsaturated double bonds which presence results in the production of unsaturated …
