Melting point: 150 to 180 °C (302 to 356 °F; 423 to 453 K) (glass temperature) ... is a water-soluble polymer compound made from the monomer N-vinylpyrrolidone. [1 ...
Hypromellose , short for hydroxypropyl methylcellulose (HPMC), is a semisynthetic, inert, viscoelastic polymer used in eye drops, as well as an excipient and controlled-delivery component in oral medicaments, found in a variety of commercial products. [1] [2] The full form of HPMC is Hydroxypropyl Methyl Cellulose.
Polyvinyl alcohol (PVOH, PVA, or PVAl) is a water-soluble synthetic polymer. It has the idealized formula [CH 2 CH(OH)] n. It is used in papermaking, textile warp sizing, as a thickener and emulsion stabilizer in polyvinyl acetate (PVAc) adhesive formulations, in a variety of coatings, and 3D printing. It is colourless (white) and odorless.
The tables below provides information on the variation of solubility of different substances (mostly inorganic compounds) in water with temperature, at one atmosphere pressure. Units of solubility are given in grams of substance per 100 millilitres of water (g/(100 mL)), unless shown otherwise. The substances are listed in alphabetical order.
Melting point: 70 °C (158 °F; 343 K) [4] Boiling point: 265 °C (509 °F; 538 K) [4] Solubility in water. 1.1 ... Toggle the table of contents. Butylated ...
Melting point: 116 to 117 °C (241 to 243 °F; 389 to 390 K) Solubility in water. Very slightly soluble in water; freely soluble in ethanol ... Flash point: 178.1 °C ...
Soluble in chloroform and other chlorinated hydrocarbons. [10] Biocompatible and hence is suitable for medical applications. Melting point 175 °C., and glass transition temperature 2 °C. Tensile strength 40 MPa, close to that of polypropylene. Sinks in water (while polypropylene floats), facilitating its anaerobic biodegradation in sediments.
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
