| titleOfInvention | Elastomer for temporary finger flexor tendon prosthesis and a method of production of elastomer |
| abstract | 1. An elastomer for a temporary finger flexor tendon prosthesis, characterized by foldingnis made of a thermoplastic phthalic elastomer of formula I, in which it is alternately locatednthere are rigid oligo (butylene terephthalate) segments with a molecular weight of 220 to 2500nand flexible segments in the form of a dimerized fatty acid having 36 C atomsnin the molecule, the weight ratio of the rigid segments to the flexible segments in the chainnpolymer is 80:20 to 26:74.n5. Method of producing an elastomer for a temporary prosthesis of flexor tendons in the fingers,ncharacterized in that the thermoplastic phthalic elastomer is obtained by transesterificationn1,4-butancoliol dimethyl terephthalate to mono- or oligomers of butylene terephthalate weighingnmolecular weight 310 to 550 and subsequent polycondensation with the dimerized fatty acid containingn36 carbon atoms per molecule, the molar ratio in the transesterification reactionndimethyl terephthalate: 1,4-butanediol is as 1: 1.5 to 1: 2, and during polycondensation the rationmolar molar amount of dimethyl terephthalate used for transesterification to dimerizednfatty acid is 1: 1 to 1: 11.3, the transesterification and polycondensation reaction is carried out bynin the presence of the catalyst in an amount of 0.05 to 0.5 g per 1000 g of reaction mixturenand excipients in an amount of 0 to 5 g per 1000 g of reaction mixture, transesterification temperaturenis from 145 to 220 ° C and the polycondensation temperature is from 225 to 275 ° C andnduring the polycondensation, reduced pressure is applied to (1 torr, 133.322 Pa over a period of 20 ton90 minutes, and then the obtained product is subjected to extraction and after removing the extracting substancensterilization. |
