    Dissolving Polymer Balls

    I actually have a chemistry drgree but it was a long time ago and i never worked with polymers. Nor do i know which polymer you were using. However i know that in plumbing history there have been major efforts to make chlorine safe plastic pipes. Look up " The effects of chlorinated water on polymeric water distribution systems". My father was a health officer at a remote military post. They got a shipment of (at the time) "modern" toilet seats. They worked great until they had an outbreak of a bug that required washing the seats with chlorine disinfectant. Then they had to post guards because some vandal was breaking the seats. The explanation that he finally got was that the disinfectant had dissolved the plasticizers (agents added to make a brittle polymer "...see more »I actually have a chemistry drgree but it was a long time ago and i never worked with polymers.

The explanation that he finally got was that the disinfectant had dissolved the plasticizers (agents added to make a brittle polymer "plastic" meaning flexible) leaving the seat prone to breakage.

    I'd be careful where you discard the liquid. If it is a disolved plasticizer the the full polymer chains could still be there, just lacking the ability to keep a form. You dont want to create a clogged drain. I might try to use your discovery in making candles. If I could pour wax into/around a complex rigid plastic form and then dissolve out the plastic that could be interesting. The opposite of lost wax casting. I have heard of using the swollen beads like the ice is used in an ice candle. After it cools allow it to dry and shake out the small dry beads.
