Types segmentation differentiates the market by polymer architecture and functionalization pathways. The primary type is the homopolymer blend, where styrene units dominate the backbone, delivering high rigidity and thermal resistance; this variant captures the largest share due to its widespread use in structural adhesives. The second type, random copolymer, intersperses allyl alcohol units randomly, enhancing polarity and adhesion to polar substrates, thus serving niche coating and sealant formulations. A third category, block copolymer, arranges styrene and allyl alcohol segments in distinct blocks, providing phase‑separated morphology that improves impact resistance for elastomeric applications. Finally, grafted copolymer involves post‑polymerization grafting of functional side chains, enabling tailored surface energy for specialty composites. Each type contributes proportionally to the overall market size, with homopolymer blends leading, followed by random, block, and grafted variants, reflecting the strategic selection of polymer structure to meet specific performance criteria in the market taxonomy.
