It isn't quite clear what problem you are talking about.
Scientists are always trying new recipes for a stronger polymer.
A scientist uses the information as a beginning for solving a problem.
Nuclear energy
Scientists are trying to understand the universe in which we live, in considerable detail.
Plastics and polymers are usually designed by polymer chemists/scientists and/or material scientists. People who then use these polymers or design with them, are architects and engineers.
we are still trying to fix the problem
Burning polymer waste can release harmful toxins and pollutants into the air, contributing to air pollution and adverse health effects. It also perpetuates our reliance on fossil fuels and contributes to climate change. Additionally, burning polymer waste does not address the root issue of excessive plastic production and consumption.
Scientists are often trying to find out whether certain factors changed or remained the same.
No.
In the 1960s, scientists thought that water could exist as a polymer. It was called "Polywater", and became a very popular thing to talk about. Unfortunately, by 1973 scientists concluded that there was no such thing as polywater.
