Photopolymerizable block polymers and methods of producing and using the same

A photo-curable resin comprising:

• a telechelic polymer, the telechelic polymer comprising a polymer chain including, in a polymerized form, a first monomer and a reactive end functional group located at each terminus of the polymer chain;
• and
• a reactive diluent,
• wherein the first monomer comprises a first reactive functional group and has a vapor pressure from 2 Pa to 10 Pa at 60° C. in its monomeric state,
• wherein the following conditions are met:
• (i) following 2 h heating at 90° C., the first monomer has a mass loss rate of less than 0.25% per hour at 90° C. in its monomeric state;
• (ii) a number average molecular weight of the telechelic polymer is not more than 50 kDa;
• and
• (iii) the reactive end functional group and the first reactive functional group independently comprise a photopolymerizable moiety, and
• wherein the photo-curable resin is capable of being 3D printed to form an article.
