In addition to the four types of nylons produced commercially, several similar polymers were studied. Properties generally fall within the range of properties of the commercial nylons, and production volume will be determined by raw material costs
Significant progress is reported, although no radically new principles were developed. Diffusion i n liquids and interfacial and convection phenomena are active fields of investigation. Piogress has been made in application of theoryand equipment design
