epoxy resin polyglycoside - based cured polymers and process for the preparation are described . a particular epoxy resin precursor is the diglycidyl ether of bisphenol a . a particular glucose based polymer is a glucose malic acid ester - vinyl copolymer . the polymers have a degree of biodegradability because of the polyglycoside as well as elevated temperature stability and are useful in transportation vehicle settings . natural source fillers , such as cellulose fibers , which are treated or untreated , exfoliated clays or exfoliated graphite can be used .
