Description
Summary:Polymers have had a significant increase in the industrial field, and polycarbonates (PCs) are an example. PCs have important properties such as high impact resistance, high heat capability, hardness, toughness, optical clarity, heat resistance, abrasion resistance and high refractive index. PCs with these properties have a variety of applications, for example, astronaut helmets, CDs/ DVDs, automobile parts, bulletproof windows, ophthalmic lenses and welding masks. In the present work we report the synthesis and characterization of network polycarbonates, based (1,1'-biphenyl)-4,4'-diyldiallylcarbonate (I) and hexa(4-allylcarbonatephenoxy) cyclotriphosphazene (III). The polycarbonates were obtained by bulk polymerization technique. The polymers obtained with thermal initiators showed degrees of cross-linking greater than 80%. The PCs obtained have thermal stability to 250 °C. The polycarbonate obtained from the monomer III showed a limiting oxygen index of 46.3%, therefore this polymer can be considered potentially useful as flame-retardant.
