Abstract
Complexation between hydroxyl containing polystyrene (PS), i.e., PS(OH) and polycaprolactone (PCL) by hydrogen bonding in solutions was studied by viscometry and laser light scattering. Formation of the complex strongly depended on hydroxyl content in PS(OH) in solution. In toluene, polymer coils existed independently when hydroxyl content in PS(OH) was less than 5 mol% while components formed complexes when hydroxyl content reached 8 mol%. No complexation was found in tetrahydrofuran (THF) even when hydroxyl content went up to 20 mol%. A combination of dynamic and static light scattering showed that in toluene solution, PS(OH) with 26 mol% of hydroxyl formed complex aggregates with higher mass and density but smaller hydrodynamic volume than PS(OH) containing 8 mol% of hydroxyl did.
