“…The dependence of the rate of polymerization on the paraffin content in mixtures containing MMA, THF, and MA in the proportions indicated for experiment 6 (Table I) passes through a maximum at 80% paraffin content; see Figure 1. This course corresponds to measurements of reaction rates made by Chapiro during polymerization of MMA (12) and lauric methacrylate (13). initiated by gamma radiation at very low temperatures (-196 and -78'C.).…”

We investigated the polymerization of methyl methacrylate, initiated by decay products of the complex formed by maleic anhydride and tetrahydrofuran and by the action of visible light. The polymerizations were effected in solid and melted paraffin at temperatures of 6 to 60°C., mostly with an 80% paraffin content. The solid‐paraffin mixtures showed high polymerization rates, a higher efficiency of photoinitiated polymerization, and an entire lack of thermal polymerization.

In den Jahren seiner Tatigkeit am Weizmann Institute of Science begann G. M . J . Schmidt seine Arbeiten uber die Beziehungen zwischen der Struktur organischer Kristalle und der in ihnen stattfindenden chemischen Reaktionen, ein Forschungsvorhaben, das sich in der Folge als aufiergewohnlich fruchtbar erwiesen hat. So wuchs seine ,,Festkorper-Gruppe" und wurde divergenter ~ Rontgenstrukturanalytiker, Organiker, Spektroskopiker und schlieRlich sogar Theoretiker wirkten mit. Professor Schmidt starb 1971. Als eines der Mitglieder dieser Gruppe folge ich nun der Einladung, uber neuere Entwicklungen auf meinem Interessengebiet zu berichten.Ein GroRteil der bisher untersuchten Reaktionen organischer Kristalle wird durch Licht oder andere Strahlung induziert. Dies ist eine naturliche Folge davon, daI3 Strahlung, ungleich den meisten chemischen Reaktanden, leicht die Oberflache des Kristalls durchdringen und so die zu aktivierenden Orte erreichen kann. In diesem Beitrag sollen einige der in der Photochemie organischer Kristalle wirksamen Prinzipien aufgezeigt und anhand von Beispielen verdeutlicht werden, wobei nicht beabsichtigt ist, alle bisher untersuchten unterschiedlichen Reaktionstypen und Systeme zu erfassen.Es ist geboten, hier in Anerkennung auch eines anderen grol3en Wissenschaftlers zu gedenken, der vor kurzer Zeit verschied ~ Theodor Forster. Manche der Ideen, auf die ich im folgenden eingehe, wurzeln, wie so vieles in der jiingsten Entwicklung der Photochemie, in Professor Furstrrs fruheren Arbeiten.Angmw. Chrm. / X7. Juhrg. 1975 / Nr.

During the years that he was at the Weizmann Institute of Science the late G. M. J. Schmidt initiated and developed a very vital research program on the relationship between the structures of organic crystals and the reactions which occur in these crystals. As the program developed the “solid‐state group” became larger and more diversified—X‐ray crystallographers, organic chemists, spectroscopists, and even theoreticans had their contributions to make. Professor Schmidt died in 1971. As one of the members of this group, I here present a review of recent developments in parts of the field of interest to me. Of the reactions of organic crystals which have been studied thus far a large number are induced by light and other radiation. This is because radiation, unlike most chemical reactants, can readily penetrate the surface of the crystal, and thus reach the sites one wishes to activate. It is my aim in this article to point out some of the principles operative in the photochemistry of organic crystals. I shall choose examples to illustrate these principles and will not attempt to cover all the various types of reaction and systems which have been studied. It is appropriate at this stage to pay tribute to the memory of another great scientist who recently passed away—Theodorr Föster. Many of the ideas which I develop here are extensions of Professor Förster's earlier work, as are so many of the recent developments in photochemistry.
