Oxyethylene copolymers with chloromethyl and (alkylthio)methyl or (alkylsulfonyl)methyl side groups: Syntheses and Tg/composition relationships
Authors:Jong-Chan Lee  Morton H Litt  Charles E Rogers
Abstract:New classes of copolymers, polyoxy(chloromethyl)ethylene]/polyoxy-((alkylthio)methyl)ethylene] copolymers (CE-ATEs), polyoxy((alkylthio)methyl)-ethylene]s (ATEs), polyoxy(chloromethyl)ethylene]/polyoxy((alkylsulfonyl)meth-yl)ethylene] copolymers (CE-ASEs), and polyoxy((alkylsulfonyl)methyl)ethylene]s (ASEs) have been made for the first time. The thioether-containing polymers (CE-ATEs and ATEs) were synthesized by reacting polyoxy(chloromethyl)ethylene] (CE, poly(epichlorohydrin)) with different amounts of sodium alkanethiolates. The sulfone-containing polymers (CE-ASEs and ASEs) were synthesized by oxidizing the CE-ATEs and ATEs using m-chloroperoxybenzoic acid. The Fox equation, a linear relationship, fit the Tg/composition data for most CE-ATEs. The Tg's of the CE-ASEs showed positive deviations from those calculated using the Fox equation. The Johnston equation, in which steric and/or polar interactions between dissimilar monomeric units are considered by using TgAB (the Tg of the AB or BA dyad), fit the Tg/composition data for all copolymers in this study. © 1998 John Wiley & Sons, Inc.
