On the other hand, numerous examples are already known in which monomeric metaphosphoric esters are generated by thermolysis reactions. Most worthy of mention in this context is the gas phase pyrolysis of the cyclic phosphonate 150 which leads via a retro-Diels-Alder reaction to butadiene and monomeric methyl metaphosphate (151) 108,109, no). While most of the phosphorus appears as pyrophosphate and trimeric and polymeric metaphosphate, a low percentage (<5%) of products 152 and 153 is also found on condensation of the pyrolyzate in a cold trap containing diethylaniline or N,N,N, N,-tetraethyl-m-phenylene-diamine. The... [Pg.109]

Fiber tows are impregnated with Epon 828 (cured with m-phenylene diamine) and the prepreg cut into plies and compression molded, with 16 plies to a composite. Thin Teflon strips are inserted between plies 8 and 9 prior to molding, which initiate an interlaminar crack when the bar is loaded as a double cantilever beam. [Pg.161]

The reaction of iV-phenyl-o-phenylenediamine (10) with DMAD gives a mixture of products consisting of l-phenyl-2-oxo-3-carbomethoxy-methylene-l,2,3,4-tetrahydroquinoxaline (11) and l-phenyl-2,3-dicarbo-methoxy-l,2,3,4-tetrahydroquinoxaline (12) [Eq. (4)]. m-Phenylene-diamine and p-phenylenediamine give the corresponding bisenamines 13... [Pg.283]

Garroway, Ritchie, and Moniz 70 continued the characterization of epoxy polymers with respect to molecular motion using variable temperature, solid state C-13 NMR. DGEBA was the epoxy of interest. The DGEBA was cured with piperidine, m-phenylene diamine, hexahydrophthalic anhydride and nadic methyl anhydride. The piperidine cured DGEBA had the best resolved polymer spectra. This system... [Pg.108]

The sodium salt is then reduced, as in the preparation of m-phenylene diamine (see p. 358). [Pg.321]

A sulphuric acid solution of m-phenylene diamine is added to the solution of the diazonium salt. The orange colour is due to diaminoazobenzene sulphate (Chrysoidine). Preparation 385. [Pg.377]
