Abstract

1515902 Non-thermoplastic polymers of lauric lactam HARWE AG 19 May 1975 [21 May 1974] 21309/75 Heading C3R A polymerization product is obtained from lauric lactam which is characterized in that it does not melt on heating but disintegrates in air at between 217 and 271‹ C. and cannot be regenerated. It also differs from conventional nylon 12 in numerous other properties. In examples such polymers are obtained by apparently conventional anionic polymerization but the obtaining of the unconventional product is ascribed to the sequence of adding the catalyst to the lactam melt and subsequently adding the actuator (as such and not in another portion of lactam melt).
