  A method of modifying the overall hydrophilic or hydrophobic nature of a high molecular weight free radical addition interpolymer, which is an aziactone-functional interpolymer, with a hydrophilic or hydrophobic nucleophilic compound is disclosed. Only the surface of the interpolymer can be hydrophilized or hydrophobized, as when the interpolymer is a coating, or the modification can take place throughout the entire bulk of the interpolymer.

• Continuous process for making polymers having pendant azlactone or macromolecular moieties

  A bulk polymerization process for free radical polymerization of vinyl monomers and alkenyl azlactones or macromolecular monomers (e.g. functionalized polystyrene), in a wiped surface reactor is disclosed. Referring to Figure 1; monomer streams (5) (after purification and silica get column 2), and (7) and macromer or azlactone (8) 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.

  本发明公开了一种用于乙烯基单体和烯丙基叠氮内酯或大分子单体（如官能化聚苯乙烯）在抹面反应器中进行自由基聚合的批量聚合工艺。参见图 1；单体流（5）（经过净化和硅胶得到柱 2）、（7）和大分子单体或氮内酯（8）与自由基引发剂（9）结合形成预混料（16）。泵（18）将预混料流（22）通过静态混合器（24）输送到擦拭表面反应器（27）中。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。散装聚合工艺可将压敏胶直接从双螺杆挤出机挤出到基材上，生产压敏胶制品。
