Hi, 

1) I am looking for manufacturers of styrene-butadiene-styrene (SBS)
and styrene-isoprene-styrene (SIS) block copolymers in Eastern Europe
and Central Asia, ideally for the whole region but if this is not
specific enough then in the following countries:

 
Poland

Ukraine

Turkey

Hungary

Romania 

Please list the company, contact details for that company and if
possible how much they produce.

If you cannot find any manufacturers please explain why you have
concluded this (including what search terms, databases, websites and
other sources you tried) and why you think it is not possible to find
them.

2) I would also like a list of companies that use SBS and/or SIS,
their location and their contact details

Dear Archie, 

I suggest you'll divide your two question into two different postings
(and cancel this one, of course). This will probably improve your
chances of getting a good answer.
