Hi, Virginie:

If all the methyl groups of PP were converted to -COOH groups, the polymer
would change to poly(acrylic acid). However, poly(acrylic acid) might not be
easy to be processed as a film.
If you want your final polymer have good film formability, you may try
Nucrel® of DuPont company, which is a copolymer of ethylene and acrylic
acid.

Rgds,
Huang

Subject: [mems-talk] How to make -or buy- a PP film with COOH groups?


Hi,
I need to either make -or buy- a PP film with its methyl groups being
converted into COOH groups. Maybe that would be a PMMA film? I am not very
familiar with polymers! I am an organic chemist and can do traditional
organic chemistry.
Thanks,
Virginie
