Organic polymers can be used to create materials with very distinct properties (both good and bad). For example, thermoset materials resist heat and solvents, making them extremely durable and allowing them to be used in the oven. The downside is that, once they're made, that's it—no recycling. Thermoplastics are stable below a set temperature, but they can be melted, allowing them to be remade into new materials. Unfortunately, they don't hold up very well to solvents.
Now, researchers are saying they've created a third option, one that acts like a thermoplastic at high temperatures but can hold up to most solvents.
