WebOne of the common problems of polyester, vinylester, phenolic, epoxy, bismaleimide, and polyimide resins is their relatively high water up-take at saturation. Both phenolic and epoxy resin absorb as much as 3-20% by weight upon saturation [86–89].This relatively high water absorption is due to the presence of polar groups in these resins. WebPolyester resins are routinely diluted/dissolved in a vinyl functional monomer such as styrene and include an inhibitor to stabilize the resin for storage purposes. Polymerisation in service is initiated by free radicals generated from ionizing radiation or by the photolytic or thermal decomposition of a radical initiator.
