Description

本発明の他の目的は、樹脂の加工時や燃焼時に環境汚染を起こすハロゲン化合物を難燃剤として含まない環境親和的な熱可塑性樹脂組成物を提供することにある。
量%、芳香族ビニル系単量体30ないし95重量%、前記芳香族ビニル系単量体と共重合可能な単量体0ないし20重量%、及び加工性及び耐熱性を付加する単量体0ないし15重量%をグラフト重合して得られたグラフト共重合体20ないし100重量%と、(a2
)芳香族ビニル系単量体60ないし90重量%、前記芳香族ビニル系単量体と共重合可能な単量体10ないし40重量%、及び加工性及び耐熱性を付加する単量体0ないし30重量%を共重合して製造された共重合体0ないし80重量%とからなるゴム変性ポリスチレン系樹脂100重量部;及び(B)環状アルキルホスホン酸エステル化合物15ないし40重量部;からなる。
本発明に用いられるゴム変性ポリスチレン系樹脂は、 芳香族ビニル単量体とビニル基
含有単量体とを重合して形成されたマトリックス(連続相)中にゴム状重合体が粒子形態で分散されて存在する重合体である。そのゴム変性ポリスチレン系樹脂の製造方法はゴム状重合体に芳香族ビニル系単量体及び必要に応じて選択的に前記芳香族ビニル系単量体と共重合可能な単量体を添加して重合するのである。
又はグラフト共重合体樹脂及び共重合体樹脂を併用して製造することができるし、それぞれの相溶性を考慮して配合することが好ましい。
(a1)グラフト共重合体
グラフト共重合体に用いられるゴム状重合体は、例えば、ポリブタジエン、ポリ(スチレン−ブタジエン)、ポリ(アクリロニトリル−ブタジエン)などのジエン系ゴム、及び前記ジエン系ゴムを水素添加した飽和ゴム、イソプレンゴム、ポリブチルアクリル酸などのアクリル系ゴム、及びエチレン−プロピレン−ジエン単量体三元共重合体(EPDM)などが挙げられるが、特にジエン系ゴムが好ましく、より好ましくはブタジエン系ゴムである。ゴムの含量は、グラフト共重合体樹脂の重量のうち、5ないし65重量%であることが好ましい。
(a2)共重合体
共重合体は、前記の組成で製造されたグラフト共重合体の成分中でゴムを除外した単量体の割合と相溶性とによって芳香族ビニル系単量体とこれと共重合可能な単量体とを共重合して製造される。
共重合体樹脂(AES)、アクリロニトリル−アクリルゴム−スチレン共重合体樹脂(AAS)、及び高衝撃ポリスチレン樹脂(HIPS)などがある。
00重量%であり、共重合体樹脂(a2)は0ないし80重量%である。
(B)環状アルキルホスホン酸エステル化合物
本発明の環状アルキルホスホン酸エステル化合物は、下記の化学式1で表される。
前記式1に当該する化合物としては、例えば、メチル−ビス(5−エチル−2−メチル−1,3,2−ジオキサホスホリナン−5イル)メチルメチルホスホン酸エステル P−オキサイド、メチル−ビス(5−エチル−2−メチル−1,3,2−ジオキサホスホリナン−5イル)ホスホン酸エステルエステルP,P'−ジオキシドである。
本発明においては、前記環状アルキルホスホン酸エステル化合物をゴム変性ポリスチレン系樹脂100重量部に対して15ないし40重量部、好ましくは20ないし35重量部が用いられる。環状アルキルホスホン酸エステル化合物(B)が15重量部未満では、充
分な難燃性を発現することができず、40重量部を超えると樹脂との相溶性に劣ることになって、適用が難しくなる。
