Abstract

Se forma una composición de un precursor de ácido polimérico, tal como ácido poliláctico (PLA), que se disuelve cuando menos parcialmente dentro de un solvente de dispersión de polímero. Una emulsión puede ser de precursor de ácido polimérico que está cuando menos parcialmente disuelto dentro de un solvente y un líquido que es substancialmente inmiscible con el solvente. En ciertos casos, el peso molecular del precursor de ácido polimérico se puede reducir al formar la solución. La solución se puede usar al tratar una formación penetrada por un pozo de sondeo.
