“…Surface polymerization of GMA from CS surfaces in CS-PGMA2 gives rise to the carbonyl bands at approximately 1 730 cm À1 , as well as to the emergence of other PGMA bands, such as 1 455, 1 258, and 1 155 cm À1 . [4,25] The bands become more prominent in the CS-PGMA1 sample with a larger polymer grafting concentration compared with the CS-PGMA2, as expected.…”

Summary: In situ atom transfer radical polymerization techniques have been used to produce polymer‐grafted carbon spheres (CSs). The surfaces of as‐prepared CSs were functionalized in the presence of CS‐supported macroinitiators. The resulting materials were characterized by FTIR and NMR spectroscopy, TGA, SEM, TEM, and HRTEM. The amount of polymer grafted onto the surfaces of the spheres can be controlled by varying the monomer/initiator feed ratio. The wetting ability and dispersibility of the polymer‐grafted CSs were improved significantly, compared with crude CSs, enabling stable dispersions in organic solvents to be produced. SEM and TEM studies indicate that a uniform distribution of the carbon spheres in the continuous polymer phase can be produced.SEM image (left) of poly(glycerol monomethacrylate) grafted carbon spheres, inset shows the structure.

“…Absence of signals around 5.00 and 5.30 ppm indicated the absence of protons corresponding to the methacrylic unsaturation. The average composition of monomeric units in the copolymers was obtained from the resonance peaks in the 1 H‐NMR spectra as reported elsewhere 22…”

“…The iodinated copolymers had high initial decomposition temperature and were stable up to 250°C. Grafting with highly sterically hindered iodine atoms would have decreased the mobility of the polymeric chains thereby reducing the thermal decomposition 22. These thermal characteristics enable the copolymers to be processed by any fabrication techniques that depend upon plastic flow at high temperature, thereby making them potential candidates for biomedical applications.…”

Poly(glycidyl methacrylate‐co‐ethyl methacrylate) and poly(glycidyl methacrylate‐co‐butyl methacrylate) random copolymers (with 50–50 mol % of monomers) were made radiopaque by grafting iodine moieties through the ring opening reaction of the epoxy groups. The percentage weight of grafted iodine in the copolymers was found to be as high as 19%. The iodinated copolymers showed higher glass transition temperature and thermal stability in comparison with the parent copolymers. Iodinated copolymer of poly(glycidyl methacrylate‐co‐ethyl methacrylate) has improved glass transistion temperature than iodinated poly(glycidyl methacrylate‐co‐butyl methacrylate). Radiographic analysis of these iodinated copolymers showed excellent radiopacity. The in vitro cytotoxicity tests revealed cytocompatibility with cells. These radiopaque copolymers are expected to find application as dental and orthopedic cements. © 2012 Wiley Periodicals, Inc. J Appl Polym Sci, 2012

“…In 1974, Kalal [33] illustrated that the post-polymerization modification via epoxide ring opening can be catalyzed by a tertiary amine (TEA) and reported up to 80% conversion of epoxide groups of polyGMA with carboxylic acids in the presence of TEA. While amines are most frequently employed for the post-polymerization modification of polymers bearing epoxide groups, epoxide groups themselves are reactive toward, for example, alcohols and carboxylic acids [33,35]. A drawback of epoxide-functionalized polymers is that they are prone to cross-linking on modification with primary amines because of the reaction between the secondary amines formed after the epoxide ring opening with another unreacted epoxide group [36].…”
