Answer:
The viscosity of polymers A) increases as the cross-linking increases within the polymer.
Step-by-step explanation:
A cross-linking increases the viscosity of the polymer. Cross-link is the bond that links properly, one polymer to other. The viscosity is highly increased because it connects the separate gel polymers together and tightly.
As cross-linker links the polymer together so the actual molecular weight of the polymer is increased, which significantly increases the viscous property of the element. Not only viscosity, the cross linking also increases the strength of the compound.
