摘要：
The purpose of the present invention what provide a kind of whole bubble property, the homogenieity of premixed liquid, excellent in stability and with the intermiscibility of various composition also excellent new polyether-polysiloxane block copolymer composition and its manufacturing method, surfactant comprising the copolymer compositions etc. and Polyurethane foaming body.The polyethers of the present invention-polysiloxane block copolymer composition contains: (A) polyethers-polysiloxane block copolymer,Its intramolecular has the following general formula (1): [changing 1]-[- SiR2O- (SiR2O) a-SiR2-CH2-CH (CH3)-CH2-O (CxH2xO) y-CH2-CH (CH3)-CH2-] n- represented structural unitAnd its terminal groups is the alkenyl etc. for being bonded what polyether moiety； And the single methanol organic compound of (B) liquid,Its for (B1) end hydrogen by alkyl replaces and another end with second level alcohol hydroxyl group low polymerization degree glycol ether compound,Or the advanced alcoholic compound with branched alkyl of 12 or more (B2) carbon number； And the polyethers-polysiloxane block copolymer composition is without dimethyl the polysiloxane more than quality of ingredient (A).本發明之目的在於提供一種整泡性、預混液之均質性、穩定性優異、而且與各種成分之相溶性亦優異之新穎聚醚-聚矽氧烷嵌段共聚物組合物及其製造方法、包含該共聚物組合物之整泡劑等、及聚胺酯發泡體。本發明之聚醚-聚矽氧烷嵌段共聚物組合物含有：(A)聚醚-聚矽氧烷嵌段共聚物，其分子內具有下述通式(1)：[化1]-[-SiR2O-(SiR2O)a-SiR2-CH2-CH(CH3)-CH2-O(CxH2xO)y-CH2-CH(CH3)-CH2-]n-所表示之結構單元，且其末端基為鍵結於聚醚部分之烯基等；及(B)液狀之單醇有機化合物，其為(B1)末端氫被烴基取代且另一末端具有二級醇性羥基之低聚合度之二醇醚化合物、或(B2)碳數12以上之具有支鏈烷基之高級醇化合物；且該聚醚-聚矽氧烷嵌段共聚物組合物不含成分(A)之質量以上之二甲基聚矽氧烷。
