Poly(ethylene oxide)-poly(propylene oxide)poly(ethylene oxide) (PEO-PPO-PEO) triblock copolymers were immobilized on thin fluorocarbon films with a structure very similar to poly(tetrafluoroethylene) (PTFE) using a microwave argon plasma. Fourier transform infrared attenuated total reflection and sp

Pluronic surfactants, PEO-PPO-PEO triblock copolymers, have been investigated widely due to their protein-resistant properties in applications as coatings for implants and in controlled drug release systems. We have studied a wide range of these copolymers, varying in both PEO and PPO block size, by
Films of LDPE containing 1-10 wt % of various polymeric additives were prepared by different techniques. Three poly(ethylene-graft-ethylene oxide)s synthesized by grafting poly(ethylene-co-acrylic acid) with poly(ethylene oxide) monomethyl ether (MPEO), and two pure MPEOs having molecular weights 75
