A polylactic acid tubular bended reactor, printed by fused deposition modeling with a short and narrow residence time distribution, air-cooled, and with dead volumes below 5 vol% was integrated into a modular reaction system enabling product changes in the running system. Continuous, redox-initiated emulsion copolymerizations of styrene - butyl acrylate and of vinyl acetate - neodecanoic acid vinyl ester were successfully performed with 20 and 40 wt% monomer in the feed. Copolymerizations had an ambient starting temperature with a mean residence time of 5 and 15 min, conversions were between 81 and 99%. The resulting emulsions were stable with Zeta potential values up to –132.0 mV and no product adhesion to the reactor wall was found. A stable steady state of the reaction plant was also obvious from thermal imaging, showing an invariant temperature profile along the 3D-printed reactor. The high versatility of the reactor system was shown by a grade transition between the copolymer systems with 20 wt% monomer content.

通过熔融沉积模型印刷的聚乳酸管式弯曲反应器，具有短而窄的停留时间分布，风冷，死体积低于5 vol％，已集成到模块化反应系统中，从而可以在运行系统中进行产品更改。苯乙烯-丙烯酸丁酯和乙酸乙烯酯-新癸酸乙烯基酯的连续，氧化还原引发的乳液共聚合成功地在进料中以20和40重量％的单体进行。共聚反应的起始温度为环境温度，平均停留时间为5至15分钟，转化率在81％至99％之间。所得乳液稳定，Zeta电位值高达–132.0 mV，没有发现产品粘附到反应器壁上。根据热成像，反应装置的稳定状态也很明显，显示沿着3D打印的反应器的不变温度曲线。反应器系统的多功能性通过单体含量为20 wt％的共聚物体系之间的梯度过渡来显示。
