Abstract
Abstract A process is described that results in the production of a hydrophilic air-drying polymer system suitable for increasing the inter-fiber bonding in a fibrous substrate material. The process comprises passing air through a monomer maintained at a temperature below about 30 DEG C., said monomer having at least two activated unsaturations, until a desired viscosity increase has been achieved.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
110 words
A process for the production of a hydrophilic air-curing polymer system which comprises passing oxygen through a monomer maintained at a temperature below 30° C., said monomer having a structure comprising at least two unsaturations, with no more than three of said unsaturations being adjacent in the molecule, at least one of said unsaturations being α, β or β, γ to a nucleophilic group capable of activating the unsaturation towards oxidative polymerization and selected from the group consisting of --O--, --S--, --CON<, --COO-- >C═C<, --SO 2 N<, --SO 2 -- and >NCN, so as to polymerize the monomer oxidatively and raise the viscosity of the system to a desired level.
Claim 2
Dependent Claim
110 words
A process for the production of a hydrophilic air-curing polymer system which comprises passing oxygen through a monomer maintained at a temperature below 30° C., said monomer having a structure comprising at least two unsaturations, with no more than three of said unsaturations being adjacent in the molecule, at least one of said unsaturations being α, β or β, γ to a nucleophilic group capable of activating the unsaturation towards oxidative polymerization and selected from the group consisting of --O--, --S--, --CON<, --COO-- >C═C<, --SO 2 N<, --SO 2 -- and >NCN, so as to polymerize the monomer oxidatively and raise the viscosity of the system to a desired level.
