GPC characterization of deuterated, hydrogenated and mixture of both PNIPAM polymers (THF was used as eluent and PS was used as standard). M n and M w are the number average and mass average molecular masses and M p is the molecular mass of the highest peak.

Sample Name M n M w M p Polydispersity Index

Hydrogenated PNIPAM 88000 104000 114000 1.18
Deuterated PNIPAM 96000 105000 106000 1.10
Mixture of deuterated and hydrogenated PNIPAM 92000 104000 109000 1.14
