Interpenetrating polymer network and method for making the same

A method for making an interpenetrating polymer network, comprising:

• providing a first monomer, a second monomer and an initiator, wherein the first monomer is
• the second monomer is
• each “R1”, “R2” and “R3” comprises —C═C— group or —C≡C— group, “R4” is an alkyl group or a hydrogen (H), “m” and “n” respectively represents an integer number, and a molecular weight of the first monomer or the second monomer is greater than or equal to 100 and less than or equal to 800;
• mixing the first monomer, the second monomer and the initiator to form a mixture, wherein the first monomer in the mixture is less than or equal to 50% of the second monomer by weight;
• and
• polymerizing the first monomer with the second monomer to form the interpenetrating polymer network.
