Unique, highly branched polyisobutylenes (PIB) were prepared via quasiliving carbocationic copolymerization of isobutylene and styrene (St) monomers. The junction points were formed by Friedel-Crafts self alkylation of PSt segments by the carbocation

Aromatic poly(1,3,4-oxadiazole-amide-ester)s were prepared by polycondensation reaction of diacid chlorides containing preformed ester groups with aromatic diamines containing 1,3,4-oxadiazole units. These polymers were easily soluble in N-methylpyrr

Controlled synthesis of a new thermoplastic elastomer (TPE), poly(isobutylene-g-styrene) (PIB-g-PSt) was achieved by quasiliving atom transfer radical polymerization (ATRP). A new commercially available butyl rubber containing bromobenzyl moieties wa

The conditions of the preparation of formaldehyde/urea (F/U) resins have been supervised with the aim to reduce formaldehyde emission by influencing the ratio of methylene/dimethylene-ether-bridge linkages in the product. The most crucial point of th

Gel permeation chromatography calibration of ultra-styragel columns for additive polyimide-siloxane copolymers was developed using peak assignments. The results show that polystyrene (PS) calibration can be used with good approximation for the sample

The reaction of bisphenol A-diglycidyl ether (BADGE) with butane-1,4-diol (BD) in the presence of Mg(ClO4)2 leads to linear and branched oligomers. The formation ratio of these products depends on the reaction temperature. In experiments at 100°C, a
