A method for producing stabilized polymers, exhibiting enhanced thermal stability, which comprises polymerizing a mixture comprising: a monomer comprising an allyl-containing group which is bonded to primary and/or secondary hydroxyl groups on a saccharide, preferably a long chain (C3-C20) allyl-containing ether group on the hydroxyl group; and one or more monomers selected from methacrylate ester monomers, acrylate ester monomers, acrylamide monomers and styrene monomers, in amounts sufficient to produce a polymer exhibiting enhanced thermal stability. Polymers having enhanced thermal stability ane obtained using a monomer comprising an allyl- containing group which is bonded to primary and/or secondary hydroxyl groups on a saccharide, as a novel stabilization crosslinking agent. In addition, a method of using non-crosslinking sucrose-based monomers, preferrably having a methyl, allcyl or crotyl ether on at least one of the hydroxyl groups of sucrose, in polymerization processes, and non-crosslinked polymers having enhanced thermal stability obtained using these non-crosslonking sucrose-based additives are provided.
