Abstract
The novel polyguanamines were synthesized by condensation reaction of bisguanamines with α,ω-dibromoalkanes in the presence of sodium hydride. The polyguanamines having inherent viscosities of 0.1—0.2 dl g−1, were obtained quantitatively. They began to lose weight around 400—480°C in air. The abilities as polymeric phase transfer catalyst of resulting polyguanamines were also investigated. They could use as effective phase transfer catalysts for the reaction of 1-bromooctane with potassium thiocyanates in toluene-water systems.
