Abstract
processo para extrair polímeros, preferencialmente poliolefinas, de material residual contendo polímero, processo de reciclagem de resíduos, material polimérico e uso deste e método para analisar o teor de material polimérico em material residual contendo polímero. a presente invenção se refere a um processo para extrair polímeros, preferencialmente poliolefinas, de material residual contendo polímero compreendendo as etapas de: fornecer material residual contendo polímero compreendendo material poliolefínico; o material residual contendo polímero entrar em contato com um solvente não polar (s) compreendendo pelo menos um hidrocarboneto, opcionalmente hidrocarboneto halogenado, tendo de 4 a 10 átomos de carbono, para formar uma composição (c); aquecer a composição (c) a uma temperatura de dissolução (t) na faixa de 135 a 200 °c e uma pressão (p) na faixa de 0,1 a 5 mpa por um período de 5 min a 5 h (m), para obter uma solução compreendendo o solvente (s) e o material poliolefínico dissolvido no solvente (s) e um material não dissolvido (u); separar o material não dissolvido (u) da solução; separar o material poliolefínico da solução e, opcionalmente, separar o solvente (s) da solução.
