Resumo: Among thermoset polymers on the market, there is a crosslinked polyethylene (PEX), which is used for high voltage cable encapsulation. A large amount of waste is generate and disposed in this process, causing burden of production and environmental hazards. Thus, this project has proposed PEX chemical modification by sulfonation reactions, which consists in the insertion of SO3H groups in its structure. The Influences of the microwaves pre-irradiation, time of reaction and concentration of free SO3 in sulfuric acid were studied by FTIR-ATR, DRX and ICP. As a result, PEX-SO3H presented to be a strong cationic resin. The best results were that obtained in 30-minute reaction and sulfonic acid with 65% of free SO3. The microwave pre-irradiation was not effectiveness in this process. The PEX-SO3H obtained in this work shows at about 97% of efficiency in remove Ca2+ from water, which proves it can be used on water treatment. Although cost-benefit analysis was not satisfactory, this study expands new possibilities for thermoset recycling.

Nesse processo, uma grande quantidade de resíduos é gerada e descartada, onerando a produção e prejudicando o meio ambiente. Desse modo, este trabalho propôs a modificação química do PEX por meio de reações de sulfonação, que consistem na introdução de grupos SO3H em sua estrutura. Estudou-se a influência da pré-irradiação em micro-ondas, do tempo de reação e da concentração de SO3 livre no ácido sulfúrico fumegante por FTIR-ATR, DRX e ICP. Pelos resultados obtidos verificou-se que PEX-SO3H pode ser classificado como uma resina fortemente catiônica. Os melhores resultados foram obtidos com 30 minutos de reação e 65% de SO3 livre sem pré-irradiação em micro-ondas. Apesar da avaliação econômica não ter sido satisfatória, esse estudo abre novas possibilidades para a reciclagem de termofixos.Entre os termofixos existentes no mercado, encontra-se o polietileno reticulado (PEX), que é utilizado no encapsulamento de fios de alta tensão.
