The macromolecular colloids of the following are :

I. Starch solution

II. Sulphur sol

III. Gold sol

IV. Synthetic rubber     

Macro-molecular colloids:– substance form large molecular whose dimensions are comparable to these of colloidal particles. Such molecules have very high molecular masses and are termed as macromolecular colloids. When such substance is dispersed in suitable dispersion medium, the resulting colloidal solutions are known as Marco-molecular colloids.

For example, starch, proteins gelatin, cellulose, nucleic acid etc. synthetic polymers such as polyethylene, polypropylene, synthetic rubber etc. also form Macromolecular colloids when dispensed in suitable solvents.
