Formulations for advanced polishing pads

A method of forming a polishing article, comprising:

• depositing a plurality of composite layers with an additive manufacturing system to reach a target polishing article thickness, wherein depositing the plurality of composite layers comprises:
• dispensing one or more droplets of a curable resin precursor composition onto a support, the curable resin precursor composition comprising:
• a first resin precursor component that comprises a semi-crystalline radiation curable oligomeric material, wherein the semi-crystalline radiation curable oligomeric material is a semi-crystalline aliphatic polycarbonate urethane acrylate oligomer;
• a second resin precursor component that comprises an acrylate monomer mixture, comprising:
• a monofunctional acrylate monomer selected from isobornyl acrylate, 3,3,5-trimethylcyclohexyl acrylate, tetrahydrofurfuryl acrylate, or combinations thereof;
• and
• a multifunctional acrylate monomer selected from dipropylene glycol diacrylate, 1,4-butanediol diacrylate, 1,3-butanediol diacrylate, or combinations thereof, wherein the acrylate monomer mixture is present from 70% to 80% by weight based on a total weight of the curable resin precursor composition;
• and
• a photoinitiator present from 0.5% to 2.5% based on the total weight of the curable resin precursor composition, wherein the curable resin precursor composition has a viscosity within a range from about 10 cP to about 30 cP at 70 degrees Celsius that enables the curable resin precursor composition to be dispensed to form a portion of the polishing article by the additive manufacturing system;
• exposing the one or more droplets of the curable resin precursor composition to electromagnetic radiation to at least partially cure the curable resin precursor composition;
• and
• repeating the dispensing and exposing to build a 3D-relief on the support;
• and
• solidifying the plurality of composite layers to form a pad body.
