Collagen Vinyl Monomers

In medical applications the monomers assemble to form collagen fibers fibrils.

Collagen vinyl monomers.

A monomer is a triple helix of three protein molecules polypeptide chains with non helical ends. Sometimes polymers are made from bound groups of monomer subunits up to a few dozen monomers called oligomers. This soluble collagen consists primarily of individual monomers. The purified telopeptide poor collagen monomers are polymerised and then cross linked with d ribose.

Collagen extracted from tannery wastes was modified by grafting it with molecular chains formed by polymerizing vinyl and acrylate monomers. Collagen is made up hieracharcal components from the smaller units of individual tc monomers that self assemble into the macromolecular fibers. In type 1 collagen monomers make up microfibrils which then make up fibris. The collagen is derived from pepsin treated porcine tendons.

Collagen powder and goat skins were grafted with different vinyl monomers using the ceric ion technique. Using collagen as the raw material methyl acrylate and vinyl acetate as the soft and hard monomers ammonium persulfate as the initiator a surface sizing agent was prepared by the emulsion polymerization method to modified the collagen. The graft copolymers were characterized by infrared spectra and electron microscopy. The novel collagen product obtained in this manner was.

One use is to plump up the skin remove wrinkles. Collagen extracted from leather waste was modified with maleic anhydride. Collagen for medical use is commonly produced by digestion of bovine skin. The risk of a hypersensitivity response to the product is less than 1 and the product does not require skin testing prior to use.

In medical applications the monomers assemble to form collagen fibers fibrils. One use is to plump up the skin remove wrinkles. Examples of oligomers include collagen and liquid paraffin. Then using ammonium persulfate as an initiator by pre modifying collagen reacted with styrene and ethyl acrylate monomers a vinyl grafted collagen sizing agent vgcsa for paper was prepared.

The product was fda approved in 2008 for the treatment of mid to deep facial wrinkles and the cosmetic effect persists up to one year after administration narins et al. To qualify as an oligomer the properties of the molecule need to change significantly if one or a few subunits are added or removed. This soluble collagen consists primarily of individual monomers. A monomer is a triple helix of three protein molecules polypeptide chains with non helical ends.
