Poly Acrylic Acid (PAA)
Poly Acrylic Acid (PAA)
(OP)
Hello,
I'm using acrylic acid and a thermal initiator to polymerize it. What should the curing time and the curing temperature be for Poly Acrylic Acid? Thanks!

The normal procedure is to follow the raw materials manufacturers recommendations then experiment with small samples to start with to get a feel for it.

Polyacrylic acid, at least when I worked with it was polymerized from solution in water with a water soluble initiator.
Although now, rereading the post, the word "cure" does sound like bulk rather than solution polymerization.
It's impossible to answer the question because each thermal initiator has it's own decomposition half-time and we don't know which initiator or how much.
A wild guess would be 65C for 2 hours but Pat's right, ask the supplier.
