“…Several studies on modifications of polymers have been reported. [1][2][3][4][5][6][7] Thermal analysis is an important analytical method for understanding the structure-property relationships and thermal stability of composite materials. There have been several publications on the thermal properties of styrene polymers.…”

Polystyrene is, after polyolefins, the most widespread polymer in both industry and everyday life, successfully replacing some raw natural materials. In this study, the chemical modification of polystyrenes of different molecular weights was performed with various functional group modifiers (epichlorohydrin, maleic anhydride, and acetic anhydride) in one stage and in the medium of the cationic catalyst BF 3 ÁO(C 2 H 5 ) 2 according to previous studies. The concentration of the functional groups bonded to the aromatic ring of the polymer as a result of the chemical modification of polystyrenes of different molecular weights depended on the molecular weight of the polymer, and more functional groups were bonded to lower molecular weight polystyrene. The effects of the functional groups bonded to the structure of the polymer on the thermal properties of modified polystyrene were investigated. The polystyrene that was modified by maleic anhydride was more stable against thermal destruction at high temperatures.

“…The quantity of functional groups in the products obtained was determined by titration methods [ 12] and the results are given in Table 1. The adhesion capability of the polyfunctionalized polystyrene coatings was determined by the 'lattice method' [12,13]. For this, a solution of polymer containing 10% toluene was prepared and the prepared solution was deposited on the metal (steel of moderate carbon content with dimensions 70 x 100 x 1 mm) surface.…”

Novel functionalized polystyrenes having groups such as epichlorohydrin, epoxy, acetyl, C=C double bond, and carboxyl were synthesized by the reaction of polystyrene with epichlorohydrin, unsaturated hydrocarbons, and organic anhydrides in the presence of Lewis acid catalysts. The adhesion capability and corrosion resistance of the new synthesized functionalized polystyrenes to metals under various conditions were investigated. A very good relationship was observed between the quantity of functional groups bonded to the aromatic rings of the polystyrenes and the adhesion and corrosion resistance properties of the polyfunctionalized polystyrenes. It was also observed that the new polyfunctionalized polystyrenes obtained by chemical modification with maleic anhydride, acetic anhydride, isoprene, butadiene, and epichlorohydrin in the presence of cationic catalysts resulted in high adhesion and anti-corrosion properties.

In this study, primary modification of polystyrene (PS) was carried out with maleic anhydride using the Friedel-Crafts reaction. Its secondary modification was realized through esterification of modified polystyrene (MPS) containing a carboxyl group with various alcohols in the presence of Amberlyst-36 as a heterogeneous catalyst. The heterogeneous catalyst gave moderate yields, whereas the reaction catalyzed by a homogeneous catalyst did not occur. The amount of carboxyl groups in the structure of MPS and unreacted carboxyl groups in the structure of the esterified MPS (EMPS) was found by using a chemical titration method for the determination of esterification yield. Some important reaction parameters were assigned to optimize the esterification process. FT-IR, 1 H NMR, and thermogravimetric studies indicate that the esterification reaction was successfully realized for each alcohol in the presence of the heterogeneous catalyst. The results demonstrated that both the acylation reaction and esterification reaction can be carried out to obtain a significantly functionalized polymer. C 2012 Wiley Periodicals, Inc.
