titleOfInvention |
Biostable elastomeric polymers having quaternary carbons |
abstract |
An article of manufacture and method of making and implanting the article made of a polyolefin star or linear copolymer are disclosed in which the polyolefin copolymer is biostable and crack-resistant when implanted in vivo. The polyolefin copolymer is the reaction product of a rubbery component which when homopolymerized produces a polymer having a low level of hardness, and a hardening component which when homopolymerized produces a polymer having a high level of hardness. The polyolefin copolymer is elastomeric, has a hardness intermediate the low and high levels of hardness, and has a backbone in which the majority of polymer linkages along the copolymer chain are alternating quaternary and secondary carbon atoms. |
