True or False: The dissolution rate of polymers mainly depends on the diffusion rate of the solvent ( ) ?√?
The dissolution rate of polymers mainly depends on the diffusion rate of the solvent (correct)
The dissolution rate of polymers mainly depends on the diffusion rate of the solvent (correct)
The dissolution rate of polymers mainly depends on the diffusion rate of the solvent
The dissolution rate of polymers mainly depends on the diffusion rate of the solvent. Correct. According to solvent and dissolution theory, it can be seen that the ability of a solvent to dissolve polymeric materials, as well as the speed of dissolution, are determined by the affinity between solvent molecules and polymer molecules – specifically, by the ease with which the solvent can diffuse into the spaces between polymer molecules.
The dissolution rate of polymers mainly depends on the diffusion rate of the solvent (correct)
The dissolution rate of polymers mainly depends on the diffusion rate of the solvent (True)
Error: The dissolution rate of polymers depends on their molecular weight and the forces between molecules.
