【発明の名称】グラフト重合、隔離板、及び隔離板を備えた蓄電池
Document Type and Number:
Japanese Patent JP2003514135
Kind Code:
A
Abstract:
A method for producing an acrylic graft polymer on the surface of a polyolefin article is disclosed. The method comprises the steps of immersing the polyolefin article in a solution of a photoinitiator in a volatile solvent, allowing the volatile solvent in the photoinitiator solution to vaporize, immersing the polyolefin article in a solution of an acrylic monomer, and subjecting the polyolefin article, while in a suitable atmosphere, which can be air or can be inert, to ultraviolet irradiation to cause the acrylic monomer to graft to the polyolefin surface. A method which involves subjecting a polyolefin article to corona discharge, immersing the article, after corona discharge treatment, in a solution of a photoinitiator and an acrylic monomer in a volatile solvent, and subjecting the article to ultra violet irradiation to cause the acrylic monomer to graft to the polyolefin surface is also disclosed. The latter method improves the ammonia trapping capacity of the grafted article.
