I think that you are going a little fast, to support your reasoning:
- polymerization = condensation into long chains of simpler molecules. Ex: polyethylene: a large number of these small molecules in C2 (ethylene) gives a long molecule = polyethylene; or again, in the natural field, starch is a polymer of glucose
Some polymers have a network structure and adsorption capacity (on the surface) with electrical charges (such as activated carbon). But not all.
latex is an emulsion, it is not a homogeneous body; like milk, which is an aqueous solution, with lactose, proteins, including casein, etc ... and a fat (cream) dispersed in multiple micro-droplets, which, in the long run, go back to the surface (cream) or which can be separated by phyisque (centrifugation).
Milk casein can polymerize to form plastics, which have not been very successful (lactitre, caseite, etc.)
Some components of the latex coagulate ...
But I still do not see the relationship with this powder and water.
