• Continuous free radical polymerization in a wiped-surface reactor

  A bulk polymerization process for free radical polymerization of vinyl monomers in a wiped surface reactor is disclosed. Referring to Figure 1; monomer streams (5) (after purification and silica gel column 2) and (7) are combined with free radical initiator (9) to form a premix (16). Pump (18) transfers the premix stream (22) through static mixer (24) into a wiped surface reactor (27). The reactor can be a counter rotating twin screw extruder which produces polymer stream (36) without the need of solvent and using residence times much shorter than prior art solution or emulsion processes. Some unique pressure sensitive adhesive acrylate polymers have been produced. They are believed to have a relatively high degree of branching. The bulk polymerization process permits the manufacture of pressure sensitive adhesive articles by extruding directly from the twin screw extruder onto a substrate.

  本发明公开了一种在抹面式反应器中进行乙烯基单体自由基聚合的批量聚合工艺。参见图 1；单体流（5）（经过提纯和硅胶柱 2）和（7）与自由基引发剂（9）结合形成预混料（16）。泵 (18) 通过静态混合器 (24) 将预混料流 (22) 输送到擦拭表面反应器 (27)。反应器可以是一个反向旋转的双螺杆挤出机，它生产聚合物流（36）时不需要溶剂，停留时间也比现有技术的溶液或乳液工艺短得多。 现已生产出一些独特的压敏型丙烯酸酯粘合剂聚合物。据信，它们的分支程度相对较高。散装聚合工艺可直接从双螺杆挤出机挤出到基材上，生产压敏粘合剂产品。

  The invention relates to thermal and pH stable catalases. One catalase of the invention was purified and characterized from Thermus brockianus . As a part of the characterization, the enzyme was compared to typical catalases from commercial sources and found to be significantly more thermal/alkaline stable than these other enzymes. The catalase purified from T. brockianus consists of four identical subunits having a molecular mass of approximately 42.5 kDa, for a total molecular mass of approximately 178 kDa.
