Responsive Polymer Nanoparticles Formed by Poly(ether amine) Containing Coumarin Units and a Poly(ethylene oxide) Short Chain

A short-chain triblock copolymer EO9-DMS7-EO9 was synthesized by couplingreaction of allyl-terminated poly(ethylene oxide) and Si–H-terminatedpoly(dimethylsiloxane). The structure and purity of synthesized copolymer wascarefully characterized. Self-assembly behavior of EO9-DMS7-EO9 triblockcopolymer in water was investigated. And it was found that along with theincrease of copolymer concentration, morphology of self-assembled aggregatestransits from sphere to rod. A plausible understanding of the morphologytransition for the investigated triblock copolymer was proposed

Initial Viscosity

Aqueous solutions of a 1 weight-per cent poly (ethylene oxide) (PEO) were degassed under vacuum, transferred to a parallel plate viscometer under a nitrogen gas blanket, and exposed to Co60 gamma radiation. The Co60 source was rated at 4000 curies, and the dose ratewas 3.8x105 rads/hr. The poly (ethylene oxide) employed in the irradiations had an initial viscosity average molecular weight of 2.1 x 106.The solutions were gelled by a free radical reaction with dosages ranging from 5x104 rads to 4.8x106 rads.
