Sorbent polymeric material suitable for capturing formaldehyde, polymeric material resulting from the capture of formaldehyde by the sorbent polymeric material, and methods for capturing formaldehyde are provided. The sorbent polymeric material has multiple aromatic rings and can be formed by initially preparing a precursor polymeric material from a polymerizable composition that contains a free-radically polymerizable spirobisindane monomer. The precursor polymeric material is subsequently treated with a sulfonyl-containing compound to form groups of formula —SO2R5 where each R5 is independently —NH2 or —NR6-Q-NR6R7. Each R6 is hydrogen or an alkyl. Each R7 is hydrogen or —C(═NH)—NH2. Each Q is a single bond, alkylene, or a group of formula -(Q1-NR6)x-Q2- where each Q1 is an alkylene, each Q2 is an alkylene, and x is in an integer in a range of 1 to 4.

The disclosure relates to polymers obtained by polymerizing in the presence of a Bronsted acid or a Lewis acid catalyst, a monomer comprising a 1,3-diisoalkenylarene, a 1,4-diisoalkenylarene, or mixtures thereof. The polymer comprises at least one of repeat units (A), (B), (C), and (D); wherein R 1 is H or a C1 - C8 alkyl group.
The polymers have high T g and exhibit good solubility in non-polar solvents, forming substantially gel-free solutions. The polymers are useful for producing crosslinked materials having good physical properties. The crosslinked materials are valuable for further downstream uses, such as copper clad laminates.
