Abstract:
The present invention relates to flame retardant polymer compositions which comprise mixtures of melamine or guanidine phenylphosphonates and mixtures with 2, 2, 6, 6-tetraalkyl- piperidines. The mixtures are especially useful for the manufacture of flame retardant compositions based on thermoplastic polymers.
Abstract:
The present invention relates to flame retardant polymer compositions which comprise mixtures of phosphinic acid salts and dihydrophospho-phenantrene (DOPO). The mixtures are especially useful for the manufacture of flame retardant compositions based on polyfunctional epoxides and epoxy resin compositions that result in laminates with excellent surface characteristics and reduced delamination tendency.
Abstract:
The present invention relates to flame retardant polymer compositions which comprise mixtures of phosphinic acid salts and dihydro-oxa-phospho-phenantrene derivatives. The compositions are especially useful for the manufacture of flame retardant compounds based on polycondensates like polyesters, polyamides and polycarbonates.
