Addition of further Bisphenol A and a catalyst and heat can produce Bisphenol A glycidyl ether epoxy resins of higher molecular weight that are solid. [8] Structure of bisphenol-A diglycidyl ether epoxy resin: n denotes the number of polymerized subunits and is typically in the range from 0 to 25
Structure of bisphenol-A diglycidyl ether epoxy resin: n denotes the number of polymerized subunits and is typically in the range from 0 to 25 Increasing the ratio of bisphenol A to epichlorohydrin during manufacture produces higher molecular weight linear polyethers with glycidyl end groups, which are semi-solid to hard crystalline materials ...
Bis-GMA a typical "vinyl ester" derived from bisphenol A diglycidyl ether. This thermoset material can be used as an alternative to polyester and epoxy materials as the thermoset polymer matrix in composite materials, where its characteristics, strengths, and bulk cost are intermediate between polyester and epoxy. Vinyl ester has lower resin ...
Exceptions include bisphenol S, P, and M. "Bisphenol" is a common name; the letter following denotes the variant, which depends on the additional substituents. Bisphenol A is the most popular representative of the group, with millions of metric tons produced globally in the past decade, often simply called "bisphenol".
Tetrabromobisphenol A diglycidyl ether is an epoxy resin consisting of tetrabromobisphenol A with ether linkages to two epichlorohydrin groups. An alernative structural comparison is as brominated form of bisphenol A diglycidyl ether. It is a brominated aromatic chemical used principally for giving flame retardant properties to materials.

Diglycidyl ether itself is extremely toxic, and can prove fatal or cause permanent damage if inhaled or consumed orally. As a class of compounds, there are a number of them available commercially with much lower toxicity profiles. [3] [4] One such example is epoxy resin itself Bisphenol A diglycidyl ether.
