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

A multifunctional monomer according to the formula:

• wherein:
• each instance of R1 and R2 are independently C1-C15 alkyl, C2-C15 alkenyl, or C3-C6 cycloalkyl,
• -[A]- is —(CRARB)n—;
• each instance of RA or RB is independently H, C1-C15 alkyl, C2-C15 alkenyl, or a moiety corresponding to the formula:
• -L- is a linking group selected from the group consisting of alkylene, alkenylene, or alkoxy-(alkylene), each of which may be optionally branched and each of which may be optionally substituted by alkyl or C1-C15 alkoxy each of which may be optionally branched;
• R3 is independently selected from the group defined in R2 above;
• and
• each instance of n is independently an integer from 3 to 6;
• and
• each instance of Q is —O— or a direct bond.

A multifunctional monomer according to the formula:

• wherein:
• each instance of R1 and R2 are independently C1-C15 alkyl, C2-C15 alkenyl, or C3-C6 cycloalkyl,
• -[A]- is —(CH2)n—[CY]—(CH2)n;
• each instance of n is independently an integer from 1 to 25;
• each instance of Q is —O— or a direct bond;
• and
• each instance of —[CY]— is an alkenyl, haloalkyl, cycloalkyl, halo cycloalkyl, or aryl-(alkyl) group.
