E1202 (Polyvinylpolypyrrolidone) (PVPP, crospovidone) is a highly cross-linked modification of PVP.
Polyvinylpyrrolidone (PVP) is a water-soluble polymer made from the monomer N-vinylpyrrolidone:.

One such commercial product is called Polyclar.

E1202 (Polyvinylpolypyrrolidone) is short for E1202 (Polyvinylpolypyrrolidone) which is a polymerized and water/beer insoluble version of the soluble compound PVP (polyvinylpyrrolidone), a nylon-type polymer that has an even higher affinity for chemical bonding with polyphenols than the proteins present in beer have.
This gives E1202 (Polyvinylpolypyrrolidone) excellent properties as a chemical stabilizer for beer.
If finely granulated, high surface area PVPP is dispersed in beer, a very high proportion of the dissolved polyphenols in the beer will bind to the PVPP particles, subsequently to be filtered out.
Brewers wish to remove these polyphenols because they will otherwise with time react with beer proteins, forming insoluble complexes that will make the beer hazy.
This type of stabilizer is referred to as an adsorbent.
