Overview

Processing of aromatic polyimides synthesized from traditional diamines and dianhydrides has always been a limiting factor in their widespread use. Decreasing the molecular weight of theses polyimides facilitates processing due to higher solubility and lower viscosity which, in turn, improves wetting characteristics. Higher molecular weight polyimides, on the other hand, are usually characterized by better thermomechanical properties compared to their lower molecular weight analogues. The introduction of reactive functional groups allows for a controlled polymerization where the resultant oligomeric polyimides can be easily processed and the properties associated with high molecular weight structures can be reclaimed upon a subsequent curing process. This webinar will serve to review this elegant way of combining processability and performance, with special emphasis on the use of acetylenic groups in varnish and coating manufacturing. Case studies featuring various polyimide formulations will be presented to illustrate these improvements.

Key Takeaways

  • Learn the basics of polyimide formulating
  • Understand how novel crosslinkers can be combined with diamines and dianhydrides to improve processing and performance of polyimides, specifically in electronic applications
  • See the technology in action as demonstrated by case studies
