Description
本出願は、米国特許仮出願第61/097,936号(2008年9月18日出願)および米国特許仮出願第61/146,856号(2009年1月23日出願)(これらの内容は各々、参照により本明細書中に組み込まれる)の利益を主張する。
定義
漸増塩濃度レベルでのPVA中の溶媒溶解度を測定するために、平衡/飽和試験を実施した。2%PVA水溶液中の塩化ナトリウム重量%を変更しながら、酢酸エチルおよび塩化メチレンの飽和溶解度(重量%)を個別に試験した。図1から分かるように、塩化ナトリウム含量が増大すると、2つの有機化合物の飽和溶解度は減少した。約15重量%塩化ナトリウム含量で、PVAは溶液の塩析を開始した。同様の傾向は、図2に示されるような1%PVA水溶液を用いて観察される。
