Document Type and Number:
WIPO Patent Application WO/2012/165525
Kind Code:
A1
Abstract:
Provided is a method for modifying the surface of vulcanized rubber or thermoplastic elastomers that can impart excellent sliding properties and durability in repeated sliding and maintain sealing without using expensive self-lubricating resins. The invention relates to a surface-modifying method in which vulcanized rubber or thermoplastic elastomers are the objects for modification, the surface-modifying method comprising a Process 1 for forming a polymerization-starting point on the surface of the object for modification, and a Process 2 for radical polymerizing monomers with the polymerization-starting point as an origin and growing a polymer chain on the surface of the object for modification.
