Multifunctional monomers, methods for making multifunctional monomers, polymerizable compositions and products formed therefrom

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), aryl, aryl-(C1-C15 alkyl), or alkoxy —(C1-C15 alkyl), each of which may be optionally substituted by C1-C15 alkyl, halo-(C1-C15 alkyl), C3-C6 cycloalkyl, halo-(C3-C6 cycloalkyl), aryl, aryl —(C1-C15 alkyl), C1-C15 alkoxy, C1-C15 alkylthio, hydroxyl, nitro, azido, cyano, acyloxy, carboxy, or ester;
• -[A]- is independently selected from a polybutadienyl 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 linking group, or a dimethyl benzene linking group;
• m is an integer from 1 to 25;
• and
• each instance of Q is independently selected from —O— or a direct bond.
