Implication

Laboratory investigation demonstrates earlier onset of autoacceleration in free-radical polymerization containing predissolved polymer, highlighting diffusion limitations on termination kinetics.

Key Points

Determine how the presence of predissolved polymer influences the onset and kinetics of autoacceleration during free-radical polymerization.
Monitored free-radical polymerization rates across systems containing varying initial concentrations of predissolved polymer.
Tracked reaction conversion thresholds and kinetic profiles to evaluate changes in diffusion-controlled chain termination.
Predissolved polymer substantially shifts the critical onset of autoacceleration toward lower conversion values.
Increased initial solution viscosity restricts radical chain diffusion, suppressing termination rates and driving elevated overall polymerization rates.
