Patent ID: 8642671

Claim:
A method for making an interpenetrating polymer network, comprising: providing a first monomer, a second monomer and a thermo-initiator, wherein a formula of the first monomer is a formula of the second monomer is each “R 1 ”, “R 2 ” and “R 3 ” comprises —C═C— group or —C≡C— group, “R 4 ” 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 thermo-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 putting the mixture into a protective gas, and heating the mixture at a temperature for a period, to polymerize the first monomer with the second monomer to form the interpenetrating polymer network under the thermo-initiator.
