Closed-cell crosslinked sponges of varying densities are prepared from an admixture of a vulcanizable elastomer, vulcanizing ingredients selected from sulfur or sulfur donor compounds together with metal oxides and/or sulfur vulcanization accelerators and t-alkylhydrazinium salt and/or carbonylhydrazine. The crosslinked sponges have uniform cellular structures and are easily prepared with the desired density.
不同密度的闭孔交联海绵是由可硫化弹性体、硫化成分(选自硫或硫供体化合物、金属氧化物和/或硫硫化促进剂)以及 t-烷基肼盐和/或羰基肼的混合物制备而成。交联海绵具有均匀的细胞结构,易于制备所需的密度。
