Synthesis, characterization, and complexing properties of a polymethacrylate bearing pendant macroheterocyclic structures
Autor: J. E. Herweh
Publikováno v: Journal of Polymer Science: Polymer Chemistry Edition. 23:2767-2778
The synthesis of a polymerizable methacrylate bearing the dibenzo-18-crown-6 moiety (5) was effected in three steps by condensation of 3,4-dihydroxybenzaldehyde with 1,2-bis[2′-(2″-chloroethoxy)ethoxy]benzene (2), reduction of the resulting 4-for

Novel polyurethanes with macroheterocyclic (crown-ether) structures in the polymer backbone
Autor: J. E. Herweh
Publikováno v: Journal of Polymer Science: Polymer Chemistry Edition. 21:3101-3114
The synthesis of a functionalized crown ether was accomplished in two steps by condensing 3,4-dihydroxybenzaldehyde with bis(2-chloroethyl)ether and subsequent reduction of the reaction product, bis(formylbenzo)-18-crown-6 (4) to a diol (5). Polyuret

Poly-2-oxazolidones: Preparation and characterization
Autor: W. Y. Whitmore, J. E. Herweh
Publikováno v: Journal of Polymer Science Part A-1: Polymer Chemistry. 8:2759-2773
Poly-2-oxazolidones were synthesized by the 1,3-cycloaddition of bisglycidyl ethers to diisocyanates with the use of N,N-dimethylformamide and lithium chloride as solvent and catalyst, respectively. A variety of arylene and alkylene diisocyanates and

The synthesis and characterization of some 2,1,6-triaryl and alkylsulfonylhydrazido-s-triazines
Autor: J. E. Herweh
Publikováno v: Journal of Heterocyclic Chemistry. 3:70-73
2,4,6-Trialkyl- and triarylsulfonylhydrazido-s-triazines (I) have been synthesized by the reaction of cyanuric chloride with a variety of sulfonylhydrazides in a hydrocarbon solvent. The subject compounds (I) were characterized by elemental analysis,

The Effect of Cross-Linking on the Dynamic Mechanical Properties of an Incompatible, Segmented Polyurethane
Autor: J. E. Herweh, J. L. Work, C. A. Glotfelter
Publikováno v: Polymer Alloys ISBN: 9781468408768
In recent years we have developed an interest in heterogeneous polymeric systems. Of particular interest have been block copolymers, specifically those prepared by low-temperature condensation techniques and providing for thermoplastic semirigid mate
