El Origen del Plástico en Mesoamérica

Varias culturas mesoamericanas tenían conocimiento para crear polímeros (plásticos) desde hace 3,500 años

Flourishing from at least 2,000 B.C. to the Spanish invasion in 1521 in what is now parts of Mexico and Central America, the Mesoamerican civilization engineered the properties of latex from the native Castilla elastica tree.

A sticky liquid that dries to a brittle solid, natural latex, which contains an oily chemical called isoprene, was mixed with juice from the morning glory species Ipomoea alba.
