It can be produced by mixing and kneading the acrylate polymer and the compounding agent with a usual mixer.
It can also be produced by mixing the raw material components in a solution or a dispersed state, but the production method of the polymer composition is not particularly limited. The acrylate polymer composition of the present invention can be formed into a sheet and used as it is. However, it is preferable to use the acrylate polymer composition by supporting it with a suitable base material because of easy handling. When the acrylate polymer is produced by solution polymerization, the polymer solution is used. When the polymer is solid, it is dissolved in a solvent such as a mixed solvent of toluene / ethyl acetate, and is difficult to dissolve in these solutions. The fuel and, if necessary, other additives are added and sufficiently dissolved or dispersed to prepare a uniform solution or dispersion. The substrate is not particularly limited, and a material suitable for the intended use of the polymer composition may be selected, and examples thereof include a paper tape, a plastic tape, and an aluminum tape. The flame-retardant pressure-sensitive adhesive tape coated with the acrylate polymer composition of the present invention can be produced in the same manner as a normal pressure-sensitive adhesive tape. For example, a solution of the polymer composition is directly applied to a support and dried. And a method in which a solution of the polymer composition is applied to release paper, dried, and then transferred to a support. The tape may be single-sided or double-sided.

で用いて難燃性を良好にすると粘着性が著しく低下し、
実用に供し得ないことが分かる。From the results shown in Table 1, it can be seen that the polymer composition of the present invention retains the vibration damping property and the tackiness (indicated by the peel strength) and has good flame retardancy. on the other hand,
In Comparative Examples, the halogen-containing phosphate ester-based flame retardant, the halogen-containing flame retardant or the phosphoric acid ester-based flame retardant used alone to improve the flame retardancy, the adhesiveness is significantly reduced,
It turns out that it cannot be put to practical use.
【００２１】[0021]
【発明の効果】以上の本発明によれば、難燃性を有し、
粘着性を保持した制振性の重合体組成物が提供される。
従って、この組成物は車両（ドアパネル、フェンダーパ
ネル、天井パネル、トランクリッド等の）、電気機器、
産業用ケーシング、パーティション、ダクト等の制振材
として有用である。According to the present invention described above, it has flame retardancy,
Provided is a damping polymer composition which retains tackiness.
Thus, this composition can be used in vehicles (such as door panels, fender panels, ceiling panels, trunk lids, etc.), electrical equipment,
It is useful as a vibration damping material for industrial casings, partitions, ducts, etc.
