Os silicones (\"polissiloxanos\") s\u00e3o utilizados numa vasta gama de aplica\u00e7\u00f5es industriais, desde os cosm\u00e9ticos \u00e0 ind\u00fastria aeroespacial.<\/p>\n\n\n\n

\"No entanto, durante a sua s\u00edntese, podem formar-se oligossiloxanos c\u00edclicos, pequenas mol\u00e9culas algumas das quais s\u00e3o classificadas como t\u00f3xicas para o ambiente e suspeitas de serem desreguladores end\u00f3crinos\",<\/em> recorda o CNRS.<\/p>

Sob a dire\u00e7\u00e3o de um investigador do CNRS, uma equipa de cientistas do Laborat\u00f3rio de Heteroqu\u00edmica Fundamental e Aplicada (CNRS\/Universidade de Toulouse Paul Sabatier), da Elkem Silicones e do Departamento de Qu\u00edmica da Universidade Aut\u00f3noma de Barcelona desenvolveu um processo de s\u00edntese de silicones a partir de siloxanos c\u00edclicos de uma forma mais limpa e ecol\u00f3gica, evitando a forma\u00e7\u00e3o destas impurezas no produto acabado. <\/p>\n\n\n\n
