| titleOfInvention | Method for producing new biologically tolerated polymers |
| abstract | ABSTRACT OF THE DISCLOSURE The invention is concerned with a method for producing polymers which are biologically acceptable, because of their elastic properties due to a system of conjugated double bonds in their molecule, and their hydrophilic properties due to the presence of -OH groups in their molecule. This method comprises polymerizing monomers containing at least 60 mole % of dienols having 5 - 10 carbon atoms and at least one -OH group, preferably in the presence of a solvent, according to a radical mechanism or an ionic coordination mechanism, by using an azo initiator, or in the presence of a catalyst consisting of a mixture of an polyalkyl aluminium with Rh acetylacetonate, Co acetylacetonate or TiCl3, respectively, with the proviso that when the polymeri-zation is carried out according to an ionic coordination mecha-nism, the -OH groups of the dienols are previously blocked in a reversible manner by reaction with Cl-Si(CH3)3. Soluble polymers can be prepared by polymerization to a low conversion degree or by polymerization at high dilution, or in the presence of chain transfer agents such as CBr4, mercaptans, etc... Three-dimensional, cross linked polymers can be prepared by polymerization in the presence of a cross linking agen or by cross linking of the soluble polymers, especially if the polymer contains both -OH groups and double bonds. |
