Abstract
Official abstract text for this publication.
Provided are surface-modified rubbers or surface-modified thermoplastic elastomers, such as catheters, syringe barrels, tubes of medical instruments, and mudguard fenders, and methods for modifying the surface of rubber or a thermoplastic elastomer, wherein a lubricant layer is firmly bonded to the surface of medical devices such as catheters, syringe barrels, and tubes of medical instruments to impart lubricity to the surface and, further, improve the durability of the lubricant layer on the surface, thereby suppressing deterioration of the sliding properties. Included is a surface-modified rubber or a surface-modified thermoplastic elastomer each having a surface at least partially treated by polymerization of a monomer in the presence of a thermal polymerization initiator.
First claim
Opening claim text (preview).
1 . A surface-modified rubber or a surface-modified thermoplastic elastomer each having a surface at least partially treated by polymerization of a monomer in the presence of a thermal polymerization initiator. 2 . The surface-modified rubber or surface-modified thermoplastic elastomer according to claim 1 , wherein the thermal polymerization initiator is present as an adsorbate on the surface. 3 . The surface-modified rubber or surface-modified thermoplastic elastomer according to claim 1 , wherein the surface is further treated, after the polymerization of a monomer in the presence of a thermal polymerization initiator, by polymerization of a monomer at least once in the presence of a thermal polymerization initiator optionally present as an adsorbate on the surface. 4 . The surface-modified rubber or surface-modified thermoplastic elastomer according to claim 1 , wherein the monomer is at least one selected from the group consisting of a hydrophilic monomer, a metal salt-containing hydrophilic monomer, and a halogen-containing hydrophilic monomer. 5 . The surface-modified rubber or surface-modified thermoplastic elastomer according to claim 1 , which comprises at least one selected from the group consisting of natural rubber, deproteinized natural rubber, silicone rubber, nylon, and polyurethane. 6 . A medical device, comprising the surface-modified rubber or surface-modified thermoplastic elastomer according to claim 1 . 7 . The medical device according to claim 6 , which is a catheter, a syringe barrel, or a tube of a medical instrument. 8 . A method for modifying a surface of rubber or a thermoplastic elastomer, comprising the step of growing polymer chains on the surface of rubber or a thermoplastic elastomer by polymerizing a monomer in the presence of a thermal polymerization initiator on the surface of rubber or a thermoplastic elastomer. 9 . The method for modifying a surface of rubber or a thermoplastic elastomer according to claim 8 , comprising, after the step of growing polymer chains, the step of further polymerizing a monomer at least once in the presence of a thermal polymerization initiator optionally present as an adsorbate on the surface.
