polyesters

Carleton Ellis was an author, and in 1923 wrote a comprehensive treatise on synthetic resins and plastics.

In 1933 he took out a patent concerning polyester resins and followed this in 1940 with the suggestion of polymerising together a liquid unsaturated polyester resin (made using maleic anhydride) and styrene monomer using a peroxide catalyst. This was the start of polyester casting resins and low-pressure laminating.

Although at the time he was mainly interested in developing surface coatings, the whole field of GRP technology has evolved from this beginning.
