Is Polyhydroxyalkanoate (PHA) a biopolymer? Where can I find information on the production of PHA?
Also, what are the polymers of vinyl chloride and styrene? I know polyvinyl chloride and polystyrene are ones, but are there any others?

You are right about the polymers from vinyl chloride and styrene.
Polyhydroxyalkanoates are a group of biologically produced, biodegradable polymers. There is an article about them in Wikipedia.

Hombre, that's what google and yahoo's search engines are for. Just search Production of PHA and List Of Polymers of Vinyl Chloride And Styrene ;-)

PHA is a biopolymer. There are many sources of PHA on the Internet. SImply google it.
I do not really understand the later question.

I don't know if it will work, but try it on another piece of cotton: Rub the stain with a raw potato. There are enzymes in potatoes that destroy some dyes - like heme. (Use a potato like an eraser to "erase" blood stains - even old set in ones.) If it starts working, you'll have to keep cutting deeper into the potato - the enzyme gets "used up" quickly. (Whether it will work depends on what the actual dye is. The ink will probably remain, but it'll be colorless.)
