Abstract

COMPOSIÇÃO POLIMÉRICA, E, CONDUTOR REVESTIDO. Trata-se de uma composição polimérica que inclui (i) um copolímero de etileno e um comonômero de alfa olefina, em que o copolímero tem uma densidade de 0,945 g/cm3 a 0,960 g/cm3, (ii) um polímero à base de etileno e (iii) polietilenoglicol. A combinação de (i) e (ii) tem um teor de comonômero de Mw alto de 3,2 % em peso ou mais com base em um peso total de (i) e (ii) combinados em relação à faixa de peso molecular médio ponderal de 105 g/mol a 105,5 g/mol conforme medido por GPC, em que 15 % em peso ou mais do peso total da composição polimérica são os (i) e (ii) combinados que têm um peso molecular na faixa de 105 g/mol a 105,5 g/mol conforme medido por GPC, em que a composição polimérica tem um teor de comonômero relevante de 0,6 % em peso ou mais e em que a composição polimérica tem uma densidade de 0,945 g/cm3 ou maior, conforme medido de acordo com a norma ASTM D792.
