Collagen Vinyl Monomers

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

Collagen vinyl monomers.

In type 1 collagen monomers make up microfibrils which then make up fibris. Collagen extracted from tannery wastes was modified by grafting it with molecular chains formed by polymerizing vinyl and acrylate monomers. One use is to plump up the skin remove wrinkles. This soluble collagen consists primarily of individual monomers.

Collagen for medical use is commonly produced by digestion of bovine skin. The graft copolymers were characterized by infrared spectra and electron microscopy. 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. 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.

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. This soluble collagen consists primarily of individual monomers. The risk of a hypersensitivity response to the product is less than 1 and the product does not require skin testing prior to use. Collagen powder and goat skins were grafted with different vinyl monomers using the ceric ion technique.

The collagen is derived from pepsin treated porcine tendons. In medical applications the monomers assemble to form collagen fibers fibrils. One use is to plump up the skin remove wrinkles. The purified telopeptide poor collagen monomers are polymerised and then cross linked with d ribose.

Sometimes polymers are made from bound groups of monomer subunits up to a few dozen monomers called oligomers. The collagen vinyl graft copolymers were hydrolyzed by both acid and enzymatic hydrolysis and the grafted vinyl polymer side chains were isolated. To qualify as an oligomer the properties of the molecule need to change significantly if one or a few subunits are added or removed. Collagen is made up hieracharcal components from the smaller units of individual tc monomers that self assemble into the macromolecular fibers.

Examples of oligomers include collagen and liquid paraffin. A monomer is a triple helix of three protein molecules polypeptide chains with non helical ends. Collagen extracted from leather waste was modified with maleic anhydride. Collagen extracted from leather wastes was modified with vinyl monomers to prepare a new collagen emulsion in this work.
