; R
7
, R
8
, R
9
, R
10
, and R
11
have the same meanings as R
1
to R

; X represents a linear or branched alkylene group having 3 to 7 carbon atoms optionally having an ether group; and “n” is an integer in the range of 0 to 100. This provides a stretchable film that hats excellent stretchability and strength, with the film surface having excellent repellency, and a method for forming the same; as well as a urethane resin used for the stretchable film; and a silicon-containing compound to be a material of the urethane resin.
本发明提供了一种含
硅化合物,其
化学式如下(1)所示:其中R1、R2、R3、R4、R5和R6分别独立地表示具有1至6个碳原子的直链、支链或环烷基基团,苯基,3,3,3-三氟丙基基团,或者由—(OSiR7R8)n—OSiR9R10R11所示的基团;R7、R8、R9、R10和R11具有与R1至R6相同的含义;X表示具有3至7个碳原子的直链或支链烷基基团,可选地具有醚基;“n”是0至100范围内的整数。这提供了一种具有优异的延展性和强度的可拉伸薄膜,薄膜表面具有优异的防
水性,以及形成该薄膜的方法;以及用于可拉伸薄膜的聚
氨酯
树脂;以及用于聚
氨酯
树脂的
硅含量化合物。
