(発明の効果)
本発明では、可塑剤の60〜96重量%、好ましくは63〜94重量%が上述した式(1)で表されるジエステル化合物であることがより好ましい。式(1)で表されるジエステル化合物を含有すると、上記炭素数16〜20の不飽和脂肪酸アルキルエステルのブリードアウトが生じ難くなる。また、中間膜とガラスとの接着をより一層穏やかな条件で行うことができ、かつ透明性により一層優れた合わせガラスを得ることができる。
攪拌装置を備えた反応器に、イオン交換水2700ml、平均重合度2400、鹸化度87モル%のポリビニルアルコール樹脂250gを投入し、攪拌しながら加熱溶解した。次に、この溶液に触媒として濃度35重量%の塩酸水溶液を0.2重量%添加し、20℃に温度調節した後、攪拌しながらアルデヒドとしてn−ブチルアルデヒド10gを添加した。その後、n−ブチルアルデヒド115gを添加したところ、白色微粒子状のポリビニルブチラール樹脂が析出した。析出10分後に濃度35重量%の塩酸水溶液を1.8重量%添加し、昇温速度20℃/時間で60℃まで加熱した後、冷却を行った。その後、中和、水洗、乾燥を行って、ブチラール化度(アセタール化度)が65.1モル%であり、アセチル基量が12.3モル%で平均重合度が3200のポリビニルブチラール樹脂Aを合成した。
イオン交換水2890gに、平均重合度1700、鹸化度98.9モル%のポリビニルアルコール275gを加えて加温溶解させた。この溶液を12℃に調節した後、35重量%の塩酸201gとn−ブチルアルデヒド148gを加え、溶液温度を12℃に保って反応生成物を析出させた。その後、45℃に3時間保って反応を完了させた。過剰の水で反応生成物を水で洗浄し、水酸化ナトリウム水溶液で中和し、さらに過剰の水で2時間洗浄し、反応生成物を乾燥させて、ポリビニルブチラール樹脂の白色粉末を得た。得られたポリビニルブチラール樹脂の平均重合度は1700、ブチラール化度は65モル%、残存アセチル基量は1モル%であった。
リシノール酸メチル
(ジエステル化合物)
テトラエチレングリコール−ジ−2−エチルヘキサノエート
(実施例1)
上記ポリビニルブチラール樹脂A100重量部に、可塑剤として上記リシノール酸メチル10重量部と、テトラエチレングリコール−ジ−2−エチルヘキサノエート40重量部とを添加し、ミキシングロールで均一に溶融混練した後、プレス成形機を用いて、150℃で30分間プレス成形を行った後、エンボスロールを通過させた。厚み0.7mmで表面に刻線状のエンボス模様(以下、「エンボス刻線」という)を持つ合わせガラス用中間膜を作製した。
実施例2〜5、比較例1及び比較例3〜5では、可塑剤の種類及びその配合割合を下記表1に示すように変更したこと以外は実施例1と同様にして合わせガラス用中間膜を作製した。
実施例7〜13及び比較例6〜11では、ポリビニルブチラール樹脂として、前述したポリビニルブチラール樹脂Bを100重量部用い、下記の表2に示すように可塑剤としてリシノール酸メチル、及びテトラエチレングリコール−ジ−2−エチルヘキサノエート(4GO)を下記の表2に示すように配合したこと以外は、実施例1と同様にして合わせガラス用中間膜を作製した。
(1)表面のベタツキ
得られた合わせガラス用中間膜の表面を手で触れることにより、表面のベタツキの有無を評価した。結果を下記表1、2に示す。
実施例及び比較例で得られた合わせガラス用中間膜を2枚の透明な湾曲ガラス板(長さ30cm、幅30cm)の間に挟持しサンドイッチ体を得た。このサンドイッチ体を、ゴムパックに入れて吸引脱気しながら0.016MPa〜0.020MPa程度の減圧下で温度90℃程度でガラスと予備接着させた。次に、サンドイッチ体を、0.016MPa〜0.020MPaの減圧下、温度100℃で20分間静置し、合わせガラスを作製した。なお、各実施例及び比較例について、それぞれ3枚の合わせガラスを作製した。
◎:20倍のルーペで観察した時、3枚の合わせガラスのいずれにも気泡の残留がなく透明であった。
◎:20倍のルーペで観察した時、3枚の合わせガラスのいずれにもエンボス刻線の痕跡がなく透明であった。
○:目視で観察した時、3枚の合わせガラスのいずれにも気泡の残留がなく透明であった。
○:目視で観察した時、3枚の合わせガラスのいずれにもエンボス刻線の痕跡がなく透明であった。
△:目視で観察した時、3枚の合わせガラスのうちいずれかのガラスにわずかにエンボス刻線の痕跡が認められた。
×:目視で観察した時、3枚の合わせガラスのうちいずれかのガラスにエンボス刻線の明瞭な痕跡が認められた。
