LCST polymers become less water-soluble as temperature rises. At low temperatures, hydrogen bonding between their ____ (I) segments and water dominates; at high temperatures, interactions between ____ (II) segments dominate.
Hydrophilic segments stabilize low-temperature hydration through favourable interactions with water, including hydrogen bonding. On heating past the LCST, dehydration and hydrophobic association favour chain collapse and phase separation. Therefore I is hydrophilic and II hydrophobic, A.
