Patent ID: 8383693

Claim:
An aerogel comprising a reaction product of: one or more first monomers, wherein each first monomer comprises an independently chosen aromatic compound having at least two unsaturated functional groups, and one or more second monomers, wherein each second monomer is independently represented by the following Chemical Formula 1: wherein, in the above Chemical Formula 1, each X 1 and X 2 is independently a (meth)acrylate group or NR″R′, wherein R″ and R′ are the same or different and are (meth)acryloyl groups, R is a substituted or unsubstituted C1 to C30 alkylene group, a substituted or unsubstituted C6 to C30 arylene group, a substituted or unsubstituted C2 to C30 heteroarylene group, or a combination thereof, each R 1 , R 2 , R 3 , and R 4 is independently hydrogen, a substituted or unsubstituted C1 to C10 alkyl group, a substituted or unsubstituted C1 to C10 alkoxy group, NR x R y , OR x , NH(CO)R x , OCOR x , a substituted or unsubstituted C6 to C18 aryl group, or CH═CR x , wherein each R x and R y is independently hydrogen or a substituted or unsubstituted C1 to C10 alkyl group, each m and n is independently an integer ranging from 0 to about 20, provided that when R is an arylene group or a heteroarylene group, each m and n is independently an integer ranging from 3 to about 20, and a and b are independently integers ranging from 0 to 4, provided that a+b is determined according to a valance of R and is 2 or more.
