Abstract
Abstract A process for producing a hydrophilic group-containing macromonomer having an ethylenically unsaturated group at the end thereof comprising reacting a hydrophilic group-containing polymer having a carboxyl group at the end thereof, with an ethylenically unsaturated group-containing epoxy compound in the presence of a hydrophilic organic solvent. According to the process of the present invention, there is provided a process for producing a hydrophilic group-containing macromonomer having an ethylenically unsaturated group at the end thereof which has been not known in the prior art.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
50 words
A process for producing a hydrophilic group-containing macromonomer having an ethylenically unsaturated group at the end thereof which comprises the step of reacting a hydrophilic group-containing polymer having a carboxyl group at the end thereof with an ethylenically unsaturated group-containing epoxy compound in the presence of a hydrophilic organic solvent.
Claim 2
Dependent Claim
50 words
A process for producing a hydrophilic group-containing macromonomer having an ethylenically unsaturated group at the end thereof which comprises the step of reacting a hydrophilic group-containing polymer having a carboxyl group at the end thereof with an ethylenically unsaturated group-containing epoxy compound in the presence of a hydrophilic organic solvent.
Claim 3
Dependent Claim
19 words
The process according to claim l wherein the hydrophilic group-containing polymer is a polymer containing hydroxyl and/or methylol groups.
Claim 4
Dependent Claim
21 words
The process according to claim l wherein the hydrophilic group-containing polymer has an average molecular weight of from l,000 to l00,000.
Claim 5
Dependent Claim
47 words
The process according to any of claims l to 3 wherein the hydrophilc group-containing polymer is produced by polymerizing a starting material based on an ethylenically unsaturated monomer containing hydroxyl and/or methylol groups in the presence of an initiator containing a carboxyl group and in a solvent.
Claim 6
Dependent Claim
31 words
The process according to claim 4 wherein the initiator is used in the polymerization step at a level of from 5 to 20 gm·moles per l00 gm·moles of the starting monomer.
