| 摘要 |
The present invention provides multifunctional monomers, including, but not limited to include multifunctional methylene malonate and methylene beta-ketoester monomers; methods for producing the same; and compositions and products formed therefrom. The multifunctional monomers of the invention may be produced by transesterification or by direct synthesis from monofunctional methylene malonate monomers or methylene beta-ketoester monomers. The present invention further compositions and products formed from methylene beta-ketoester monomers of the invention, including monomer-based products (e.g., inks, adhesives, coatings, sealants or reactive molding) and polymer-based products (e.g., fibers, films, sheets, medical polymers, composite polymers and surfactants). |

1. A multifunctional monomer having the formula: wherein: each instance of R1 and R2 are independently C1-C15 alkyl, C2-C15 alkenyl, halo-(C1-C15 alkyl), C3-C6 cycloalkyl, halo-(C3-C6 cycloalkyl), heterocyclyl, heterocyclyl-(C1-C15 alkyl), aryl, aryl-(C1-C15 alkyl), heteroaryl or heteroaryl-(C1-C15 alkyl), or alkoxy —(C1-15 alkyl), each of which may be optionally substituted by C1-C15 alkyl, halo-(C1-C15 alkyl), C3-C6 cycloalkyl, halo-(C3-C6 cycloalkyl), heterocyclyl, heterocyclyl-(C1-C15 alkyl), aryl, aryl —(C1-C15 alkyl), heteroaryl, C1-C15 alkoxy, C1-C15 alkylthio, hydroxyl, nitro, azido, cyano, acyloxy, carboxy, or ester; [A] is independently selected from a polybutadienyl linking group, a polyethylene glycol linking group, a polyether linking group, a polyurethane linking group, an epoxy linking group, a polyacrylic linking group, or a polycarbonate linking group, a polyester linking group, polytetrahydrofuran, a C3-C6 cycloalkyl linking group, a triol based linking group, or a dimethyl benzene linking group; each instance of Q represents —O— or a direct bond. |
