摘要:
3,3'-Thiobis(2,5-dihydrothiophene-1,1-dioxides) on heating with a reactive Diels-Alder dienophile undergo a reaction producing thioethers having two six-membered alicyclic rings in the molecule, such as 4,4'-thiobis(3,6-dihydrophthalic acids) or the esters, anhydrides or imides thereof, and 4,4'-thiobis-(1,2,3,6-tetrahydrophthalic acids) or the esters, anhydrides or imides thereof. Both rings of the dihydrothiophene dioxides participate in the reaction, apparently by forming a tetraene structure which co-reacts with two equivalents of the dienophile to form an adduct in which each six-membered ring has one or two olefinic double bonds. During the course of the reaction, the thioether bridge remains intact. Some of the bis(alicyclic) thioethers are readily converted to the corresponding bis(aromatic)thioethers by use of known aromatization methods and systems. Various utilities for the products of the foregoing reactions are described.

摘要:
A class of relatively low molecular-weight oligomers containing at least one isoimide group and terminal groups capable of undergoing an addition polymerization reaction. The oligomers of the present invention are characterized by excellent solubility in common solvents and a melting temperature considerably lower than their cure temperature, thus enabling the oligomers to be formed into cured polymers more slowly and at lower temperatures, all without the evolution of deletrious gases.
