Question

are polymers and PVC EXAMPLES OF THERMOPLASTICS?

Answer 1

polythene and PVC .polythene is used for making commonly used polythene bags.

Answer 2

Answer:

To ensure optimal injectivity and sweep efficiency, we focus on four key field conditions:

reservoir temperature

divalent ion concentration

salinity of injection and formation fluids, and

reservoir permeability.

Salinity and divalent ion concentration of injection and formation fluids along with reservoir temperatures affect the viscosity and stability of the solution. Harsher conditions typically require sulphonated polymers. Molecular weight selection is driven by reservoir permeability range.
