<img title="Women's Legacy logo" src="//inclusion.womenslegacyproject.eu/images/LogoWL.svg" /><hr />Existe un tipo de pl&aacute;stico que es m&aacute;s resistente que el acero y resistente al fuego. Este pl&aacute;stico, llamado Kevlar, pertenece al grupo de los llamados termopl&aacute;sticos y fue descubierto por Stephanie Kwolek, quien fue una qu&iacute;mica pionera en el campo de los materiales polim&eacute;ricos que en 1965 descubri&oacute; un pol&iacute;mero l&iacute;quido que pronto ser&iacute;a conocido como Kevlar. Tuvo una carrera llena de &eacute;xitos. Trabaj&oacute; para acercar a los j&oacute;venes a la ciencia. En sus propias palabras, &ldquo;Creo que los j&oacute;venes necesitan inspiraci&oacute;n para creer en s&iacute; mismos y no tener miedo de pensar diferente&rdquo;.

1. State the differences between thermoplastics and thermosets. <img src="//inclusion.womenslegacyproject.eu/uploads/resume/attachment/1443/Syndiotactic_polypropene.png" alt="" width="400" height="400" />
2. Draw the internal structure of thermoplastics and thermosets. &nbsp;
3. Write down 4 applications where Kevlar is used. &nbsp; 4. Classify the following types of plastics, stating if they belong to the group of thermoplastics or thermosets:
PVC
TEFLON
BAKELITE
METHACRYLATE
NYLON
MELAMINE
POLYURETHANE
CELLOPHANE
POLYETHYLENE
POLYSTYRENE
&nbsp;

Observations and context

We can relate Stephanie Kwolek's invention of Kevlar plastic to other far-reaching inventions for industry and technological progress made by women: Wifi (Hedy Lamarr), GPS (Gladis Mae West), the electronic book (Ángela Ruiz Robles), anti-reflective glass (Katharine Blodgett), vacuum packaging (Amanda Jones), fiber optic cable (Shirley Jackson), VoiP technology (Marian Croak), portable X-rays (Marie Curie) or the circular saw (Sarah Tabitha Babbitt).

Description

Type: exercises to learn about and distinguish the different types of plastics, their properties and applications, within the topic of Plastics.

Objectives: analysing the methods for obtaining plastic materials used in the fabrication of technological projects. Describing the internal structure of different plastic materials, as well as the alterations to which they can be subjected, in order to improve their properties, taking into account their intended use.
