VINYL ESTER RESINS .3.

This paper describes the effect of ethyl methacrylate (EMA) on the the rmal and mechanical properties of glass fibre-reinforced laminates of vinyl ester resins derived from diglycidyl ether of bisphenol-A and me thacrylic acid. The thermal stability and the curing characteristic of the resins were investigated by thermogravimetric analysis and differ ential scanning calorimetry. The glass transition temperature of the l aminates decreased with increase in EMA content. Dilution of vinyl est er resin with EMA resulted in a decrease in flexural strength and flex ural modulus of the laminates.
