Embodiment 1-1

[0251] In the 1L reactor, the average combined formula M H D. 20 m H Represented methyl hydrogen polysiloxane 75.25g, with the average combined formula CH 2 =C(CH 3 )CH 2 -O(C 2 h 4 O) 33 (C 3 h 6 O) 25 -CH 2 -C(CH3 )=CH 2 174.75 g of the indicated bismethallyl polyether, 250 g of dipropylene glycol monobutyl ether (BDPG) and 0.25 g of natural vitamin E were heated to 80-90°C while stirring under nitrogen flow. 0.56 g of the IPA solution (Pt concentration: 0.45% by weight) of a platinum-2,4,6,8-tetramethyl-2,4,6,8-tetravinyltetrasiloxane complex was added and reacted for 2.5 hours. Next, 1 g of the reaction liquid was collected and confirmed by the alkali decomposition gas generation method, and the reaction was completed. Thus, a 50:50 ratio containing at least the average combined formula

Embodiment 1-2

[0257] Except having replaced BDPG with propylene glycol monobutyl ether (BPG), it experimented similarly to Example 1-1. Operations such as reactivity in the synthesis reaction of the linear organopolysiloxane-polyether block copolymer are the same as in Example 1-1.

Embodiment 2-1

[0259] In the 1L reactor, the average combined formula M H D. 20 m H Represented methyl hydrogen polysiloxane 85.55g, with the average combined formula CH 2 =C(CH 3 )CH 2 -O(C 2 h 4 O) 33 (C 3 h 6 O) 25 -CH 2 -C(CH 3 )=CH 2 164.45 g of the indicated bismethallyl polyether, 250 g of dipropylene glycol monobutyl ether (BDPG) and 0.25 g of natural vitamin E were heated to 80-90°C while stirring under nitrogen flow. 0.056 g of an IPA solution (Pt concentration: 4.5% by weight) of a platinum-2,4,6,8-tetramethyl-2,4,6,8-tetravinyltetrasiloxane complex was added and reacted for 3 hours. Next, 1 g of the reaction liquid was collected and confirmed by the alkali decomposition gas generation method, and the reaction was completed. Thus, a 50:50 ratio containing at least the average combined formula

Abstract

To provide: a novel polyether-polysiloxane block copolymer composition having excellent foam stabilizing properties, homogeneity in a premixed solution, and stability, and also having excellent compatibility with various components; a method for preparing the copolymer composition; a foam stabilizer and the like including the copolymer composition; and a polyurethane foam. This polyether-polysiloxane block copolymer composition contains: (A) a polyether-polysiloxane block copolymer in which molecules have a structural unit represented by the following general formula (1), -[-SiR2O-(SiR2O)a-SiR2-CH2-CH(CH3)-CH2-O(CxH2xO)y-CH2-CH(CH3)-CH2-]n-, and the end group of which is an alkenyl group bonded to a polyether moiety; and (B) a liquid monool organic compound which is (B1) a glycol ether compound of low polymerization degree in which hydrogen at one end is substituted by a hydrocarbon group and which has a secondary alcoholic hydroxyl group at the other end thereof, or (B2) a higher alcohol compound having a branched alkyl group containing 12 or more carbon atoms, wherein the amount of dimethyl polysiloxane contained in the composition is less than the mass of component (A).

Description

【Technical field】 [0001] The present invention relates to a polyether-polysiloxane block copolymer containing (A) a specific structure and (B) a specific monohydric alcohol organic compound that is liquid at 5°C, and dimethyl polysiloxane A novel polyether-polysiloxane block copolymer composition containing less than the mass of component (A) and its production method. In addition, the present invention relates to a surfactant, a foam stabilizer (having a function as a foam control agent and a foam stabilizer, the same applies hereinafter), a cosmetic raw material, and a cosmetic containing the composition. And, the present invention also relates to a polyurethane foam-forming composition containing the composition and a polyurethane foam obtained therefrom. 【Background technique】 [0002] As (AB) n-type polyether-modified silicon, there is known a hydrosilylation reaction of (1) organopolysiloxane containing SiH groups at both ends and (2) polyether containing methallyl gr...
