Yes, glue is a polymer.
When water is added to a polymer, it can cause the polymer chains to swell and increase in volume. This is because water molecules can interact with the polymer chains, promoting their separation and expansion. In some cases, this can lead to the polymer absorbing water and becoming softer or more flexible.

No, it's not the same thing. Ethylene is a gas used to produce polyethylene (solid). "Polymer grade" is just a purity label for ethylene gas, means that this ethylene is pure enough to be used in polyethylene (or other polymer) production.
Glycerin is not a polymer because it is a simple compound, not a chain of repeating units like a typical polymer. Glycerin is a triol compound that does not exhibit the characteristics of a polymer structure.
No, it is not necessary to let lithium polymer batteries run dead before charging. In fact, it is better to avoid completely draining the battery as it can be harmful for its longevity. It is recommended to charge lithium polymer batteries before they reach a very low charge level for optimal performance and lifespan.
