Pardubice

A sulfonated ion exchanger catalyst (Research Institute of Synthetic Resins and Varnishes, Pardubice, Czechoslovakia) was a macroreticular styrene-divinylbenzene copolymer containing 25% divinylbenzene and 2.4 meq/g of —SO3H groups. It was dried prior to using at 90°C/14 Torr. The BET surface area, determined in a dry state, was 49 m2/g, and the mean pore size was around 100 A. 

Shortly afterwards and independently, the group of Sterba in Pardubice (Czechoslovakia) published a series of papers on the kinetics of acid-base and isomerization equilibria of substituted benzenediazonium ions. Initially they used classical methods for rate measurements (Machackova and Sterba, 1972 a, 1972 b Jahelka et al., 1973a), then later stopped-flow techniques (Jahelka et al., 1973b).

Trade name of a plastic explosive (-> Plastic Explosives) from the Czechoslovakian firm Synthesia, Pardubice-Semtin. 

Since about 1950 polymer-bonded (or plastic-bonded) explosives (PBX) have been developed in order to reduce sensivity and to facilitate safe and easy handling. PBX also show improved processibility and mechanical properties. In such materials the crystalline explosive is embedded in a rubber-like polymeric matrix. One of the most prominent examples of a PBX is Semtex. Semtex was invented in 1966 by Stanislav Brebera, a chemist who worked for VCHZ Synthesia in Semtin (hence the name Semtex), a suburb of Pardubice in the Czech Republic. Semtex consists of varying ratios of PETN and RDX. Usually polyisobutylene is used for the polymeric matrix, and phthalic acid n-octylester is the plasticizer. Other polymer matrices which have been introduced are polyurethane, polyvinyl alcohol, PTFE (teflon), Viton, Kel-F and various polyesters.
