“…In this sense, the preparation of smart polymeric matrices with inorganic compounds can provide additional functions to the pure polymers used in many applications [16][17][18]. Nevertheless, the problems associated with the lability of the metal-carbon bonds partially stopped this progress, but new regulation and advances in macromolecular chemistry have renewed interest in these structures [19,20].…”

The functionalization of smart polymers is opening a new perspective in catalysis, drug carriers and biosensors, due to the fact that they can modulate the response regarding conventional devices. This smart response could be affected by the presence of organometallic complexes in terms of interactions which could affect the physical chemical properties. In this sense, the thermoresponsive behavior of copolymers based on N-isopropylacrylamide (NIPAM) could be affected due to the presence of hydrophobic groups and concentration effect. In this work, the functionalization of a copolymer based on NIPAM and dopamine methacrylamide with different amounts of bis(cyclopentadienyl)titanium (IV) dichloride was carried out. The resulting materials were characterized, showing a clear idea about the mechanism of functionalization through FTIR spectroscopy. The thermoresponsive behavior was also studied for various polymeric solutions in water by UV–vis spectroscopy and calorimetry. The hydrophobic interactions promoted by the organometallic complex could affect the transition associated with the lower critical solution temperature (LCST), specifically, the segments composed by pure NIPAM. That fact would explain the reduction of the width of the LCST-transition, contrary to what could be expected. In addition, the hydrophobicity was tested by the contact angle and also DNA interactions.

Linear, soluble copolymers containing titanium are of interest for use in targets for inertial‐confinement fusion (ICF) experiments because the titanium is a useful spectroscopic probe for studying the nuclear fusion process. Some suitable copolymers have been prepared from vinyl titanate monomers and styrene via free‐radical polymerization. Soluble copolymers with molecular weights between 70,000 and 100,000 daltons containing 0.1 atom % titanium can be reliably prepared. These copolymers have been incorporated into targets used in inertial‐confinement fusion experiments at Lawrence Livermore National Laboratory. Attempts to prepare identical copolymers using macromolecular modification were unsuccessful and yielded insoluble materials upon reaction of the functionalized copolymers with titanium(IV) isopropoxide. © 2000 John Wiley & Sons, Inc.
