“…The new materials are found to be favourable in all the requirements of SSNTD materials, such as transparency, track development upon chemical etching with alkali metal hydroxides, viewing of the tracks under optical microscope and stablility of the materials. The polymerization profile of this hexafunctional allylic monomer is in accordance with the kinetic model proposed by Dial et al [10].…”

“…Dial et al [10], the allylic polymerization is highly exothermic in nature and the polymerization should be carried carefully and slowly for extended time period. It is also known that the allylic monomers in general and ADC monomer in particular shrink by about 14% of its volume during the process of solid polymer formation.…”

“…The exotherm and the shrinkage collectively lead to cracking of the films if proper care is not taken. Dial et al [10], after a careful kinetic study, have proposed some kinetic equations by which constant rate polymerization cycle can be defined with a constant rate of catalyst decomposition, as well as monomer conversion, thus resulting in a constant rate of heat evolution. Although Dial et al have studied this rate of polymerization for a tetra-functional allylic monomer, ADC, we thought of extending their idea to a hexafunctional allylic monomer and mixture of allylic monomers.…”

Abstract-A novel monomer, N-allyloxycarbonyl diethanolamine-bis(allylcarbonate), has been synthesized and cast-polymerized for the first time to obtain poly-[N-allyloxycarbonyl diethanolaminebis(allylcarbonate)] (PNADAC), which was used successfully as a solid-state nuclear track detector for alpha particles and fission fragments. The monomer has been synthesized from diethanolamine by reacting allyl chloroformate in a one-step process. The kinetics of its polymerization reactions were studied. A co-polymer with allyl diglycol carbonate (ADC) was also prepared after studying the kinetics of the polymerization reaction. It was found that the homo-and co-polymers are more sensitive towards alpha particles as compared to the commercially available CR-39 ™ track detector.

“…The mold was then placed in a polymerization bath, and the polymerization was carried out using the heating time cycle and by periodic tightening the moulds. This is required since the allylic polymerization is an exothermic process accompanied by shrinkage in monomer volume, during the process of solid polymer formation (Dial and Gould, 1945;Dial et al, 1955). Using the constant rate polymerization cycle, homopolymer films of TDONM were prepared.…”

synopsisDiallyl 2-substituted succinates, obtainable via the addition of alkenes or alkylaromatics to maleic anhydride, undergo intramolecular cyclization during polymerization to low molecular weight prepolymers. The amount of this cyclization and the properties of the cured prepolymers are profoundly affected by the structure of these 2-substituents. Thus, the degree of cyclization decreases with these substituents in the order: aralkyl and isobutyl > unhindered alkenyl > alkyl > hindered alkenyl. Properties of thermosetting molding compounds based on these prepolymers are inferior to those of poly-(diallyl phthalate) molding compounds.
