“…Boron catalysts have also been employed to synthesize polybenzylidene from phenyldiazomethane and random copolymers and cross-linked networks from diazomethane and other diazoalkanes. For example, the copolymerization of diazomethane and 9-anthryldiazomethane afforded a luminescent polymethylidene copolymer . Recently, Shea and co-workers have utilized boron catalysis to produce poly(ethylacetalmethylidene) oligomers from ethyl diazoacetate .…”

Homopolymerization of alkylarylcarbenes derived from diazirine monomers that featured benzyl alcohol or phenol residues was found to lead to the production of soluble hyperbranched poly(aryl ether)s. The polymerization process was influenced by the solvents employed, monomer concentration, and the reaction time. An increase in the monomer concentration and reaction time was found to lead to an increase in the molecular weight characteristics of the resulting polymers as determined by gel permeation chromatography (GPC). The composition and architecture of the polyethers were determined by nuclear magnetic resonance (NMR) spectroscopic analysis and were found to be highly complex and dependent on the structure of the monomers used. All of the polymers were found to contain ether linkages formed via carbene insertion into O−H bonds, although polymers derived from phenolic carbenes also contained linkages arising from C-alkylation.

Effect of thermodynamic strength of solvent on structure formation of crosslinked copolymers

et al. 1985

The effect of the thermodynamic strength of the solvent used in the copolymerization of mono-and bifunctional monomers on the molecular-topoIogic structure of soluble copolymers with bridge bonds was investigated. The investigation was carried out taking as an example radical copolymerization of methyl methacrylate (MMA) and 9,lO-anthrylenedimethyl dimethacrylate. The presence of anthracene groups in the molecules of the crosslinking agent made it possible to follow the number of intra-and interchain bridge bonds formed in the polymer system. Toluene/octane mixtures with an octane content from 0 to 35 v01.-Vo were used as solvents of different thermodynamic strengths with respect to PMMA. It was found that over a narrow range of changes in the composition of the solvent (from 30 to 33 v01.-To of octane) the values of M, and [q] of the copolymers increase drastically. It is shown that this increase is due to an increase in the number of interchain crosslinks occurring when the strength of the solvent under the copolymerization conditions used decreases.

Formation of crosslinked polymers in the copolymerization of 9,10‐anthrylenedimethyl dimethacrylate and methyl methacrylate

1985

The formation of a crosslinked polymer during the copolymerization of mono-and bifunctional monomers was investigated choosing as an example the free-radical copolymerization of methyl methacrylate (MMA) and 9,lO-anthrylenedimethyl dirnethacrylate (1). The anthracenecontaining crosslinks permit the determination of the topological structure of soluble MMA-1 copolymers containing bridge bonds. This copolymer is formed fiist and characterized by a considerable structural heterogeneity. The intrinsic viscosity of the soluble copolymer increases sharply in a certain reaction stage and, at the same time. an insoluble copolymer fraction appears. In the formation of the gel fraction those branched macromolecules which consist of a greater number of linear components and contain a greater number of "pendent" double bonds participate fiist.
