Method for producing hydrolyzable silicon group-containing oxyalkylene polymer and curing composition thereof

摘要

The problem of the invention is to efficiently produce a hydrolyzable silicon group-containing oxyalkylene polymer which has a low viscosity while maintaining a plasticity of a cured product and which does not contaminate an area around a sealing portion and/or has no adverse effect on an adhesion. The problem is solved by a process for producing a hydrolyzable silicon group-containing oxyalkylene polymer, which comprises using, as a starting material, an oxyalkylene polymer in which a first oxyalkylene polymer having at least two active hydrogen groups and a second oxyalkylene polymer having one active hydrogen group coexist, and converting the active hydrogen groups to hydrolyzable silicon groups.
