大きく分けられる。[Prior Art] Generally, there are two methods for imparting flame retardancy to thermoplastic resins: adding and mixing a flame retardant to the resin, and modifying the resin itself using a reactive flame retardant. It can be broadly divided.

。Conventionally, various compounds have been known as additive flame retardants for thermoplastic resins. however,
These additive flame retardants have a number of drawbacks. For example, addition of flame retardants tends to reduce the mechanical properties, heat resistance stability, and transparency of resin products, and there is also the disadvantage that flame retardants bloom on the product surface. Particularly in the case of polypropylene, blooming of the flame retardant is remarkable, and no satisfactory flame retardant has yet been found.

いる。Recently, oligomeric or polymeric flame retardants with relatively large molecular weights, such as tetrabromo bisphenol A carbonate oligomer (Japanese Patent Publication No. 57-26305), have recently been used as flame retardants with less blooming.
Bromide of polyalkenylphenol (Special Publication No. 57-64
56 Publication) etc. have been proposed. When these flame retardants are added to polypropylene, they are effective against the blooming problem, but they have the disadvantage of being inferior in flame retardant effect.

ーミングが認められた。[Table 1] As is clear from the table, Examples 1 to 4 had excellent flame retardancy and no blooming of the flame retardant was observed. However, in Comparative Example 1, although the flame retardance was good, blooming was large. In Comparative Example 2, no blooming was observed, but the flame retardance was poor. In Comparative Example 3, flame retardancy was good, but blooming was observed.
