qおよびpは独立して0から10であり;
b+cが少なくとも1であるという条件であり;
但しシロキサンに富む化合物は、少なくとも25重量%のケイ素含有量を有するという条件である。
表1a-1cに関する注記
*シロキサンの修飾の場合の過剰なポリエーテル反応物を除く
**物理的発泡剤の重量を除く
表1a-cおよび3の両方について、以下のシリコーンベースの組成物が使用される:
従来の硬質フォームシリコーン安定剤:65D単位および7.5D’単位の直鎖状シリコーンヒドリドをアリルヒドロキシ末端EO/POポリエーテル上で30%ポリエーテル過剰で反応させて得られたコポリマー、ポリエーテルは、約12.8EO単位および3.2POを含む。シロキサンコポリマーは、約19%のシリコーン含有量および約11000ダルトンの数平均分子量を有する。
・シロキサンベースの組成物1から4を表2に表す。
・シロキサン組成物5:ヘキサメチルジシロキサン、またはMM
・シロキサン組成物6:未修飾のポリジメチルシロキサン、平均構造M3D7TのTタイプ
・シロキサン組成物7:MD’Mをアリルヒドロキシ末端ポリエチレンオキシドと反応させて得られた修飾シロキサン、6.6EO単位
・シロキサン組成物8:MD’Mをアリルメトキシ末端ポリエチレンオキシドと反応させて得られた修飾シロキサン、6.6EO単位
表2に関する注記
*2つのM末端あたりのD単位の平均数として29SiNMRによって決定される
**ガスクロマトグラフィーによって決定され、較正係数を使用して重量%に再計算される
***低分子量側の全積分の0.5%未満に寄与する分子量として、ゲル浸透クロマトグラフィー(GPC)により決定-ポリジメチルシロキサン標準が較正に使用される
****高分子量側の全積分の1%未満に寄与する分子量として、ゲル浸透クロマトグラフィー(GPC)によって決定-ポリジメチルシロキサン標準が較正に使用される
*****D4、D5、およびD6は、シロキサン組成物の一般的な環状残留種であり、それぞれオクタメチルシクロテトラシロキサン(D4)、デカメチルシクロペンタシロキサン(D5)、およびドデカメチルシクロヘキサシロキサン(D6)である。レベルは、組成物の液体抽出とそれに続く抽出混合物のガスクロマトグラフィーによって得られた。
結果は、主要ポリオール100部あたり1.6から2.8部の標準レベルで組み込まれた従来のシリコーン界面活性剤が、フォーム1aから1cに、24から24.5mW/m・Kの範囲の初期フォーム熱伝導率値(またはラムダ値)をもたらすことを示している。シロキサン組成物を添加していないが、24から24.5mW/m・Kの範囲内にあるフォームにて、いくらかの標準的な散乱が観察される。従来の界面活性剤レベルを5部などの非常に高い値に上げることにより、23.81mw/m・Kでのわずかに低いラムダ値を得ることができるが、それほど重要ではないと考えられる非常に小さな利点である。従来のシリコーン界面活性剤に加えて、選択された分子量のシロキサンに富む組成物を、主要ポリオール100部あたり0.2部の低いレベルで添加することにより、著しく低いフォームラムダ値が得られることが見出された。これは、本発明の態様および実施形態に含まれる、添加されたシロキサン組成物1から3または6で見ることができる。より低いまたはより高い分子量またはより低いケイ素含有量を有し、本発明の範囲外である、添加されたシロキサン組成物4、5、7、または8を使用する比較例は、そのような利益をもたらさなかった。これらの実験から生成されたすべてのフォームは、反応性(ゲル時間で定量化)やフォーム密度などの他の基本的なフォーム特性で大きな違いはない。
*シロキサンの修飾の場合の過剰なポリエーテル反応物を除く
**物理的発泡剤の重量を除く
これらのPUR配合物は、PIR配合物で得られたものと同等の効果を示す。本発明の態様および実施形態の範囲内にある添加されたシロキサン組成物2および6を用いて、対照フォーム2と比較して、0.4mW/m・K以上の有意な熱伝導率の利益が達成される。本発明の範囲外である添加されたシロキサン組成物5、7、または8を使用する比較例は、シロキサン組成物5および8のラムダ値を改善しないか、またはシロキサン組成物7について0.2mW/m・Kのオーダーのわずかな利益を示す。この場合も、ゲル時間およびフォーム密度によって定量化された反応性などの他の基本的な泡特性を生成したフォームは、著しく異なっていない。
