| titleOfInvention | Process for making reactive unsaturated polyester resins from 2-methyl-1,3-propanediol |
| abstract | A two-step process for making reactive unsaturated polyester resins is disclosed. First, an aromatic dicarboxylic acid derivative reacts with 2-methyl-1,3-propanediol (MPD) to produce an ester diol intermediate. The intermediate reacts with maleic anhydride and from about 15 to about 40 mole percent, based on the total glycol requirement, of propylene glycol. By shifting some glycol to the second step, and by using propylene glycol there, resin producers can easily make MPD-based UPR having a fumarate content greater than 85%. The resins give thermosets with improved physical properties, including excellent water resistance. |
