Description
(a1)90〜99.995%の少なくとも1種のビニル芳香族モノマー及び0.005〜10質量%のスチレンスルホン酸の塩若しくは対応するC1〜C4アルキルエステルを含有するコポリマー、又は
(a2)92〜99.995質量%のビニル芳香族(コ)ポリマー並びに、スチレンスルホン酸の塩若しくは対応するC1〜C4アルキルエステル及びスチレンと、スチレンスルホン酸の塩若しくは対応するC1〜C4アルキルエステルとのコポリマーから選択される0.005〜8質量%の生成物を含む高分子混合物から選択される(a)高分子マトリックス、並びに
(b)高分子マトリックス(a)に対して1〜10質量%の発泡剤、
を含む。
(c)平均直径30〜1000nm、表面積5〜200m2/g、硫黄含有量0.1〜100ppm及びヨウ素価5〜40mg/kgを有する、ポリマー(a)に対して0.01〜25質量%のカーボンブラック、
(d)最大寸法0.05〜100μmを有する粉末形態で、発泡した又は発泡性の、ポリマー(a)に対して0.01〜10質量%のグラファイト(天然、合成)、
(e)ポリマー(a)に対して0.01〜10質量%のハイドロタルサイト又はシリコンの無機誘導体から選択される。
水性懸濁液中において、1種以上のビニル芳香族モノマーを、任意で添加剤(c)〜(e)を含む充填剤、スチレンスルホン酸の塩若しくはエステル及び/又はスチレンと、スチレンスルホン酸の塩若しくは対応するC1〜C4アルキルエステルとのコポリマーの存在下で重合し、
このようにして得られた顆粒を分離し、
顆粒を水に再懸濁させ、球状化(spherulization)するまで加熱し、
発泡剤を懸濁液に添加し、含浸するまで顆粒を発泡剤と接触させ続け、
顆粒を再分離することを含む。
(i)スチレンスルホン酸の塩若しくは関連するC1〜C4アルキルエステル又はスチレンと、スチレンスルホン酸の塩若しくは関連するC1〜C4アルキルエステルとのコポリマー及び任意で上記の添加剤(c)〜(e)を、顆粒形態又は既に溶融状態にある、平均分子量Mw50000〜300000、好ましくは70000〜220000を有するビニル芳香族(コ)ポリマーに添加し、
(ii)任意で、ビニル芳香族ポリマーを、相対融点より高い温度にまで加熱し、
(iii)ダイを通しての押出成形前に、発泡剤(b)及びその他の考えられ得る添加剤(難燃剤等)を溶融したポリマーに添加し、
(iv)このようにして得られた高分子組成物を、静的又は動的混合要素により混合し、
(v)このようにして得られた組成物を、ダイ、切断チャンバ及び切断システムを備えた装置で顆粒化することを含む
(1)ビーズを静電気防止液剤(例えば、アミン、エトキシ化第三級アルキルアミン、エチレンオキシド/プロピレンオキシドコポリマー等)で被覆する。この薬剤によりコーティングの接着が可能になり、また懸濁液中で調製されたビーズのスクリーニングが促進される;
(2)このビーズに、場合によってはカーボンブラックと混合された、本質的に、脂肪酸とのグリセリン(又はその他のアルコール)のモノ−、ジ−及びトリエステル及びステアリン酸金属塩(ステアリン酸亜鉛及び/又はステアリン酸マグネシウム等)の混合物から成るコーティングを適用することから成る。
混合物を、閉鎖され且つ攪拌された容器内に投入する。この混合物は115質量部の水、事前に30部の水に分散させられた0.3部のリン酸三カルシウムC13−08(Budenheim社、ドイツ)、100部のスチレン、0.30部の過酸化ベンゾイル、0.25部のtert−ブチルパーベンゾエートから成る。この混合物を攪拌しながら90℃にまで加熱し、温度が80℃に達したら、5部の水に事前に溶解させた0.01部のメタ重亜硫酸ナトリウムを投入する。
