Project Title"Green" Methods of Making Vinyl Ester Resin
Track Code2015-038
Short Description

Environmentally benign “green” methodology for the synthesis of green vinyl ester resin (GVER). Utilization of starting material derived from bio-waste streams. 

Abstract

UMass Lowell researcher Dr Yongwoo Lee and his colleagues have developed an environmentally benign “green” methodology for the synthesis of green vinyl ester resin (GVER). Utilization of starting material derived from bio-waste streams (glycerol, a waste product form bio-diesel manufacturing industries), helps to improve the environment and cost sustainability of the procedure.

Background

Vinyl ester resins (VER) are high performance unsaturated resins with exceptional mechanical strength and corrosion resistance. In addition to their superior performance, these resins display lower viscosities than conventional epoxy resins resulting in significantly improved processability. Vinyl ester resins (VER) are currently synthesized by addition reaction of epoxy containing bisphenol-A diglycidyl ether (BADGE) with either meth acrylic acid or methyl methacrylate (unsaturated carboxylic acids). BADGE is currently synthesized using bisphenol A (BPA) and epichlorohydrin as starting materials.

Epichlorohydrin however, has been identified by the U.S. Environmental Protection Agency (EPA) as a hazardous air pollutant and it also features on the list of controlled chemicals by the EPA. Hence, to ensure continued environmental sustainability and improved work place safety for the synthesis of VER, an alternative route is highly desired.

Technology

UMass Lowell researcher Dr Yongwoo Lee and his colleagues have developed an environmentally benign “green” methodology for the synthesis of green vinyl ester resin (GVER). Utilization of starting material derived from bio-waste streams (glycerol, a waste product form bio-diesel manufacturing industries), helps to improve the environment and cost sustainability of the procedure. VER was synthesized in one pot and two-steps reaction protocol starting with bisphenol-A and glycerol. The resulting product was analyzed by NMR spectroscopy.

This is also an environmentally benign route for synthesis of VER formulations with a “green” reactive diluent by having side product of glycerol as a part of product mixture.

Competitive Advantages

  • Environment-friendly “Green” process
  • Synthetic steps involve the use of starting materials derived from bio-waste streams
  • Eliminates the use of toxic chemicals such as epichlorohydrin in VER synthesis
  • One pot process
  • For downstream composite: GVER has similar viscosity as the commercial resin with only half the styrene content, thereby reducing the toxic volatile organic compounds associated with manufacturing.
  • Cost-comparative

Applications

Due to their superior properties and excellent processability, Vinyl ester resins (VER) find use, either in pure form or as a matrix in fiber reinforced composites, in diverse industries, such as Transportation, Building & Construction, Marine.

  • Automotive parts
  • Corrosion resistance coatings - chemical storage tanks, pipes& ducting, fume extraction systems, gas cleaning units
  • Ship building
  • Top-coat materials (with excellent adhesion to plastics, steel and concrete)
  • Optical fiber coating
  • UV curing inks
  • Printed circuit board manufacture

Market Potential

Vinyl ester resins were first commercialized as Epocryl resins by Shell Chemical Company and later as Derakane resins by Dow Chemical Company. Currently these resins are produced predominantly by Ashland, DSM and Reichold.

The global reinforced plastic composite market is estimated to total 13.6 billion pounds in 2013, 14.3 billion pounds in 2014 and is expected to increase to nearly 17.2 billion pounds (~$92B) by 2019. This market is expected to show a compound annual growth rate (CAGR) of 3.7% through the forecast period of 2014 to 2019.
