I am trying to find polymers that are soluble in water at high temperature (above 70 degree). I know PVA is one of them. Are there any more polymers -either natural or synthetic?
Dear Kiruthika,
Try alginate in low concentration.
Best regards,

Examples of water-soluble polymers:
1) Polyacrylamide. 2) Poly(acrylic acid) . 3) Poly(methacrylic acid) but this polymer tends to precipitate upon heating. 4) Starch ,as you know, is soluble in cold water & stays soluble upon heating.
But take care, sometimes, the polymers do not have true solubility as simple compounds & they just get dispersed through the medium.
Alginate, polyacrylamide, poly(acrylic acid), poly(methacrylic acid), starch, etc. polymers are soluble in water. However, their solubility also depends on molecular weight of polymer and other structural factors. Hence as Dr. Nizar Matar said you need to taste and then finalize. It is special case for starch-out of two-only one kind of starch structure show solubility.
Additionallly Hydroxyethylcellulose + Polyox are soluable at all temperatures in water.
