Polymeric materials and their thermoset, resinous products prepared by the polymerization of a mixture containing at least two different monomeric structures selected from the group having the general formula <IMAGE> +TR CH2(OCH2)yOCH2R3 wherein each A represents a chalcogen independently selected from the group oxygen and sulfur; R1 represents a member selected from the group hydrogen, -CH2(OCH2)yOCH2-R3; each R2 represents a member independently selected from the group consisting of R1, halogen and an alkyl group of 1 to 10 carbon atoms; R3 represents a member selected from the group consisting of H, methyl, ethyl and propyl; each m represents an independently selected integer from 1 to 2; n represents an integer from 0 to 60 and y represents an integer from 0 to 3 in the presence of an acid catalyst at a temperature of from between about 140 DEG and about 165 DEG C. for from several minutes to several hours. The thermoset resinous products are obtained by further heating the aforedescribed polymeric materials at a temperature of from about 170 DEG C. to about 260 DEG C. for from several minutes to several hours. The polymeric materials are low melting solids which are useful as laminating, molding, film-forming materials which can be cured or thermoset by heat.
