I synthesized a copolymer of styrene and butadiene using a polar modifier. The expectation is that the polymer is a random copolymer (not a blocky copolymer). Is there a noninvasive characterization technique that can be used to confirm the monomer distribution in this polymer?
Dear Sravya Jangareddy, many techniques are used, NMR I think is the most used to analyse repeating units sequence distribution. Would you please specify the copolymer you are dealing with. Please check the following documents. My Regards

The book by Bovey and Mirau is an excellent resource to understand the nmr methods.
Block and random co-polymers have different solubility parameters. Probably the most useful technique would be nmr. Please see link below
