Модификация эпоксидной смолы ЭД-20 поливинилформальэтилалем

One of the methods for increasing the impact toughness of materials based on epoxy resins is modification with thermoplastics. The paper presents experimental data on the effect of polyvinyl formal ethylal (Vinyfl ex) and various curing modes on the toughness of compositions based on ED-20. The mechanism for modifying ED-20 with Vinyflex was analyzed. The data obtained are necessary for the development of domestic technology for the production of impact-resistant plastics.
