hmm...Thanks for your input. So the suggestion is to lower the agitation during polymerization? Can you let me know if there is a specific relationship or something time-based on that (so I can adjust it)?

Oh I see what you mean, I didn't mention a 600-700 rpm mechanical stir in the PVA solution.

hmmm...I was following a procedure. So..your point is each component should b added separately to the suspension solution?

the initiator is mixed with the monomer, briefly stirred, then added to the water/PVA solution

Dear, I am doing suspension polymerization of methyl methacrylate BPO-DMPT is used as initiator at room temp (~5.5wt % of monomer) PVA (I tried 99% and 88% hydrolized) as suspending agent (1wt% of water) monomer:water : 1:3.6 I fail to obtain the bead but an aggregated mass for 99% PVA and...
