Claims
- 1. A bio-compatible synthetic fiber comprising a polymer selected from the group consisting of cellulosic polymers, esterified cellulosic polymers, etherified and nitrated cellulosic polymers, polyethylene, polyamides, vinyl chlorides, the polymers and copolymers of vinylidene chloride, styrene, vinylbutyrate and gamma methylglutamate, polymers and copolymers of acrylonitrile, butadiene and isoprene, acrylates and methacrylates, and vinyl esters, said polymer having occluded therein a bio-compatible platelet-aggregation preventing agent selected from the group consisting of 4,5-diphenyl-2-bis(2-hydroxyethyl) amino oxazole, 4,8-dipiperidino-2,6-diethanolaminopyrimido-(5,4d)-pyrimidine dicumarol, and derivatives of salicyclic acid.
- 2. A fiber as claimed in claim 1 wherein said polymer is cellulose triacetate and said bio-compatible material is 4,5-diphenyl-2bis-(2-hydroxyethyl)-amino oxazole.
- 3. A fiber as claimed in claim 1 wherein said polymer is polyvinylchloride and said bio-compatible material is 4,5-diphenyl-2bis(2-hydroxyethyl) amino oxazole.
- 4. A method of producing a bio-compatible synthetic fiber which comprises adding a platelet-aggregation preventing agent selected from the group consisting of 4,5-diphenyl-2-bis (2-hydroxyethyl) amino oxazole, 4,8-dipiperidino-2,6-diethanolaminopyrimido-(5,4d)-pyrimidine dicumarol, and derivatives of salicylic acid to a solution containing a polymer selected from the group consisting of cellulosic polymers, esterified cellulosic polymers, etherified and nitrated cellulosic polymers, polyethylene, polyamides, vinyl chlorides, the polymers and copolymers of vinylidene chloride styrene, vinylbutyrate and gamma methylglutamate polymers and copolymers of acrylonitrile, butadiene and isoprene, acrylates and methacrylates, and vinyl esters to form a mixture, adding a bio-compatible surface layer forming reagent to said mixture to thereby form a spinnable solution and spinning said solution to thereby form said bio-compatible synthetic fiber.
- 5. The method of producing a bio-compatible synthetic fiber as claimed in claim 4, which includes adding 4,4'-diamino-diphenylmethane to said solution and reacting said 4,4'-diphenylmethane and polyethylene glycol bis-chloroformate during said spinning step to form a bio-compatible polyurethane, and causing said polyurethane to coat said fibers.
