3.ペンタエリスリトールジホスホネート化合物(B成分)が、下記式(2)で示される化合物である前項1または2に記載の難燃性樹脂組成物。
5.前項1~4のいずれかに記載の難燃性樹脂組成物より形成された成形品。
3,9-ビス(2-((オキソ)ジフェニルホスフィノ)エチル)-3,9-ジオキソ-2,4,8,10-テトラオキサ-3,9-ジホスファスピロ[5.5]ウンデカン、3,9-ビス(2-((オキソ)ビス(2-メチルフェニル)ホスフィノ)エチル)-3,9-ジオキソ-2,4,8,10-テトラオキサ-3,9-ジホスファスピロ[5.5]ウンデカン、3,9-ビス(2-((オキソ)ビス(3-メチルフェニル)ホスフィノ)エチル)-3,9-ジオキソ-2,4,8,10-テトラオキサ-3,9-ジホスファスピロ[5.5]ウンデカン、3,9-ビス(2-((オキソ)ビス(4-メチルフェニル)ホスフィノ)エチル)-3,9-ジオキソ-2,4,8,10-テトラオキサ-3,9-ジホスファスピロ[5.5]ウンデカン、3,9-ビス(2-((オキソ)ビス(2,4-ジメチルフェニル)ホスフィノ)エチル)-3,9-ジオキソ-2,4,8,10-テトラオキサ-3,9-ジホスファスピロ[5.5]ウンデカン、3,9-ビス(2-((オキソ)ビス(2,6-ジメチルフェニル)ホスフィノ)エチル)-3,9-ジオキソ-2,4,8,10-テトラオキサ-3,9-ジホスファスピロ[5.5]ウンデカン、3,9-ビス(2-((オキソ)ビス(3,5-ジメチルフェニル)ホスフィノ)エチル)-3,9-ジオキソ-2,4,8,10-テトラオキサ-3,9-ジホスファスピロ[5.5]ウンデカン、3,9-ビス(2-((オキソ)ビス(2,4,6-トリメチルフェニル)ホスフィノ)エチル)-3,9-ジオキソ-2,4,8,10-テトラオキサ-3,9-ジホスファスピロ[5.5]ウンデカン、
化合物が用いられているが、これらは溶融加工時にホスフィンガスを発生させ、金属部品を激しく摩耗するという金属腐食性の問題がある。本発明のペンタエリスリトールジホスホネート化合物は有機リン化合物であり、金属腐食は発生しない。

ましくは炭素数1~3のアルキル基または炭素数6~15、好ましくは6~10のアリール基を示す)および(iv)フェニル基の如き炭素数6~15のアリール基が挙げられる。
アルキルチオ基および(iv)Ar3-W1-式で表される基(ここでW1は-O-、-S-または炭素数1~8、好ましくは炭素数1~4のアルキレン基を示し、Ar3は炭素数6~15、好ましくは炭素数6~10のアリール基を示す)が挙げられる。
島津製作所製DTG-60A(熱重量測定装置)により、昇温速度20℃/minで測定した。
表2記載の各成分を表2記載の量(重量部)で配合し、15mmΦ二軸押出機(テクノベル製、KZW15)にてペレット化した。得られたペレットを120℃の熱風乾燥機にて5時間乾燥を行った。該ペレットを射出成形機((株)日本製鋼所、J75EEIII)にて12.5mm×125mm×1.6mm(1/16インチ)の試験片を成形した。
試験片の下端にガスバーナーで10秒間接炎させた後の燃焼時間を測定し、燃焼が30秒以内に止まった場合、さらに10秒間接炎させ、燃焼時間を測定した。本測定を5本実施し、全ての接炎に対する総燃焼時間と最大燃焼時間に関して比較評価を行った。
