Key Points

To determine the pH-dependent polymerization heat and rate of acrylic acid using isothermal calorimetry.
Utilized isothermal calorimetry with a time-correction method.
Measured polymerization heat and rate at varying pH levels.
Employed size-exclusion chromatography to analyze molar mass and polydispersity.
Successfully measured polymerization heat as a function of pH.
Determined polymerization rates that vary with pH.
Collected data on molar mass and polydispersity from size-exclusion chromatography.

Implication

Isothermal calorimetry measures polymerization heat and rate in poly(acrylic acid), indicating pH effects.

Abstract

Isothermal calorimetry, incorporating a time-correction method, was employed to measure the pH-dependent polymerization heat and polymerization rate of acrylic acid. Subsequent size-exclusion chromatography provided molar mass and polydispersity data.
