✦ Synopsis
New types of ecologically friendly polymer flame-retardant systems were proposed for Nylon 6,6 and polypropylene [high temperature polymer-organic char former, poly(vinyl alcohol), and silicon-inorganic system]. These systems can act in condensed and gaseous phases. The cone calorimeter and LOI tests indicated the improvement of fire-retardant properties for compositions of flame retardants with Nylon 6,6 and polypropylene in comparison with pure polymers.

## Abstract Two flame‐retardant polyesters were polymerized with two types of phosphorous flame retardants. 3‐(Hydroxyphenyl phosphinyl)propanoic acid (HPP) was used as a main‐chain type, and 9,10‐dihydro‐9‐oxa‐10‐2,3‐dicarbonylpropyl‐10‐phosphophenanthrene‐10‐oxide (DI) was used as a pendant type.
## Abstract Two kinds of flame‐retardant polymers prepared from the phosphorylation of poly(vinyl acetate) were employed to reduce the flammability of polypropylene (PP). The two flame‐retardant polymers had very different effects because of the differences in their chemical structure. Effects on f
