具有乙烯基苄醇重复单元和至少一种不同于乙烯基苄醇的其它结构的线性加成聚合物珠粒，其中乙烯基苄醇单元占线性聚合物的至少0.5重量%，及其热交联衍生物。所述珠粒通过在其形成期间或之后在自由基引发剂的存在下加热而热交联，使得在乙烯基苄醇单元的芳环之间以及在乙烯基苄醇单元与聚合物中的其它活性位点之间形成α-羟基苄型亚甲基或苄氧基交联。线性加聚物可以直接由乙烯基苄醇单体和至少一种其它单体形成，或者在由其形成线性聚合物期间通过乙烯基苄基氯的水解间接形成。交联产物可用作吸附剂、水凝胶和在制备其它吸附剂、离子交换树脂、催化剂和缓释剂中用作中间体。
Linear addition polymer beads having repeating units of vinylbenzyl alcohol and at least one other structure different from vinylbenzyl alcohol, wherein the vinylbenzyl alcohol units comprise at least 0.5% by weight of the linear polymer, and thermally crosslinked derivatives thereof. The beads are thermally crosslinked by heating during formation thereof or thereafter in the presence of a free radical initiator, such that alpha-hydroxy benzylic methylene or benzyloxy crosslinks are formed between aromatic rings of the vinylbenzyl alcohol units, and between the vinylbenzyl alcohol units and other active sites in the polymer. The linear addition polymers may be formed directly from vinylbenzyl alcohol monomer and at least one other monomer, or indirectly by hydrolysis of vinylbenzyl chloride during linear polymer formation therefrom. The crosslinked products are useful as adsorbents, hydrogels and as intermediates in the preparation of other adsorbents, ion exchange resins, catalysts and slow release agents.
