AO19 dual sensitivity pH and temperature

PolySciTech ( provides PolyVivo AO19 Poly(dimethylaminoethyl methacrylate-co-methoxy polyethylene glycol) P(DMAEMA-mPEG) (95:5). Recent testing at Akina confirmed that this polymer, when dissolved in water, has sensitivity towards both temperature as well as pH of the aqeous environment. The material degels at low pH due to ionization of the DMAEMA endgroup.  Find out more here:
