1. Preparation
1.1 Summary
Vinyl esters are obtained by adding a carboxylic acid to an epoxy resin (figure 1 ).
In practice, the epoxy resins used have a macromolecular unit of two possible types:
bisphenol A (the A in bisphenol A reminds us that it is manufactured using acetone);
novolac (novolac, also known as phenoplast, is obtained by reacting phenol and formaldehyde in an acid medium).
This is the form in which vinyl ester resins are delivered to converters.

Production
The vinyl ester market is based on corrosion resistance applications. This market has reached maturity in Europe. The growth of vinyl ester resins depends on their use in applications where their mechanical properties are more important than their corrosion resistance.
Production capacities are not known. However, it is generally agreed that world consumption exceeded...
