Natural polymers gelatin

Last years the polymeric surface - active substances began to use as modifiers of organic reagent properties. In our work the behavior of synthetic polymers (polysulphonilpiperidinilmethylenhydroxide (PSPMH), polyvinylpyrrolidone (PVP), polyamines - polyguanidine and metacide) and natural polymers (starch, gelatin) for various molecular masses are investigated. 

A related class of gels are those formed by extensive hydrogen bonding. An example is the polyethylene oxide)-poly(methacrylic acid) complex [18]. Spontaneously gelling natural polymer solutions are frequently of this type, including gelatin and native starch. 

Natural polymers modified with vinyl groups (e.g, albumin or gelatin modified with glyoldyl aorylate),... 

Natural polymers such as gelatin or albumin have been used as particulate drug delivery systems, although they are of uncertain purity and certainly have the potential for immunogenicity. 

A gelatine gel is made with warm water. Gelatine is a protein. Proteins are natural polymers (Chapter 15, p. 243) and the molecules of protein are very large. The large molecules disperse in water to form a gel.

They are made of polymeric, waxy, or other protective materials, that is, biodegradable synthetic polymers and modified natural products such as starches, gums, proteins, fats, and waxes. The natural polymers include albumin and gelatin " the synthetic polymers include polylactic acid and polyglycolic acid. ...
