A comparison is made of the chain conformational distribution of hydroxyterminated poly(propylene glycol) (PPG) and poly(ethylene glycol) (PEG) with their methoxy-terminated derivatives. The significant end-group dependence on the glass transition temperature in PPG was observed by differential scan

## Abstract Phase transition and mobility of poly(__N__βisopropylacrylamide) (PNIPA) chains with three different types of end groups (hydroxyl, carbonβcarbon double bond, and camphoric sulfonic groups) have been studied by measurements of the normal ^1^H NMR spectrum, spinβspin relaxation time, and
