Alkali-soluble polymers and process for producing same |
| abstract |
A process for producing an alkali-soluble graft polymer is disclosed. The graft polymer has at least one main chain and a plurality of side chains attached thereto. The process comprises combining at least one vinylic monomer that is capable of forming free radicals, at least one ethylenically-unsaturated carboxylic acid monomer that is capable of addition-copolymerization with the vinylic monomer in the presence of the thus-formed free radicals, and cyclic ester molecules that are capable of ring-opening in the presence of the carboxylic acid monomer, to produce a polymerizable mixture. the polymerizable mixture to subjected to a preselected temperature and pressure for causing the monomers to free-radically addition-copolymerize to form the main chain while the cyclic ester molecules graft thereon, thereby forming the side chains of the graft polymer. The process is characterized in that the main-chain and side-chain formations of the graft polymer occur substantially simultaneously. |
