Could anybody tell me how to do thermal polymerization AA (acrylic
acid). The initiator, other additives (preferably biocompatible) and the
conditions like temperature, timing, etc for the same.

I tried acrylic acid with benzoyl peroxide (initiator)and PEG and
Aerosil for thickening the same (tried with different values of
accelerator and at different temperatures like 45, 50, 90 C). As finally
I need to have thick layer of the polymer. But this cracks or polymer
might be vaporising in the oven. So no results with this.

I tried hydroquinone as inhibitor.
With some certain ratios of accelerator and inhibitor, I was able to see
some polymerisation but that also explodes into cracked solid, when I
let it remain in the oven for some more time (temp was 40 deg C).

I want to have a uniform n homogenous polymer, which could be
spincoated. Also there is need for the final material (polymer) to
withstand 120 deg C. So any suggestions or solutions are welcome.

ALSO I NEED INFO ABOUT ANY COMPANY WHICH COULD PROVIDE THE POLYMER OF
THE ABOVE DESIRED CHARACTERISTICS. I COULD BUY DIRECTLY FROM THEM.

thanks.....
