The synergistic flame-retarded effects of a similar molecular sieve [Co5(OH)2(tca)2(ina)2 (H2O)2]•4H2O(Co5) and ammonium polyphosphate(APP) on cottonwood was studied. Compared with APP added individually, when the addition of Co5 was 1.7%, THR reduced 18.3% and the mass loss reduced 7.7%. The TGA showed that the processes of losing solvent water, coordinated water, tricarballylic acid and isonicotinic acid ligands can inhibit burning and lower the weightlessness rate. The flame retardancy of APP/Co5 was superior to that used APP individually, Co5 showed good synergistic flame-retarded effects.

PA 10,10 can be flame retarded either by melt-blending the polymer with intumescent formulations or by coating it with UV-curable mixtures.

Samples of m-PPO (virgin and flame retarded) and high impact polystyrene blended with zinc and zinc borate (2ZnO·3B2O3·3.5H 2O), were pre pared. The effect of triaryl phosphate on the flame retardancy of PPO-HIPS in conjunction with zinc and zinc borate was studied. For polystyrene zinc borate shows some reduction in smoke generation. Zinc, however does not show any effect on smoke generation for high impact polystyrene. Triphenyl phosphate shows minimal flame retardancy in HIPS which is not enhanced by zinc. Addition of zinc gives an increase in oxygen index for FR m-PPO, whereas zinc borate decreases the OI values. Zinc borate may sequester triaryl phos phate and thus eliminate its vapor phase activity. Zinc borate shows a signifi cant reduction in smoke generation and rate of heat release for m-PPO.
