Description
本发明涉及通过氧杂硅杂环(oxasilacycle)的酸催化聚合和共聚合的可交联的硅氧烷。
DE102008000353A1描述了含有至少一个烷氧基甲硅烷基≡Si-O-C(R1)(R2)(R3)的可交联聚合物共混物和其用于无水硅烷交联的用途。
环状硅氧烷,诸如六甲基环三硅氧烷或八甲基环四硅氧烷可以通过使用路易斯酸(Lewis acid)或布朗斯台德酸(acid)催化而聚合以得到线性长链硅氧烷,如例如W.Noll,Chemie und Technologie der Silicone,Verlag Chemie GmbH,Weinheim,1968中所公开的。
称为氧杂环的环状甲硅烷基醚与α,ω-SiOH封端的聚二甲基硅氧烷的反应产生甲醇官能的硅氧烷,如例如DE10109842、EP629648、DE102004029259或DE 102009046254中所述。
JP 2000186103A描述具有-R-C(CH3)=CH2侧基并且用作悬浮聚合中的单体以便产生调色剂粒子的硅氧烷。
含有两个烷基、且在一些或所有硅氧烷单元上具有末端双键的聚硅氧烷迄今是未知的。
本发明提供了一种使氧杂硅杂环聚合的方法,所述氧杂硅杂环选自通式(1)和(5):
其中选自通式(1)和(5)的氧杂硅杂环与任选存在的选自通式(3)的线性硅氧烷和选自通式(3a)的环状硅氧烷的硅氧烷在酸催化剂K的存在下聚合,以形成通式(4)的化合物:
RO-Si(R7)2O[Si(R7)2O]oSi(R7)2-OR (3),
其中
R是氢、在每种情况下具有1到50个碳原子的未经取代的或经取代的烃基或酰基,
R1、R2、R1’、R2’、R1"、R2"各自是氢、卤素、氰基、OH,或在每种情况下具有1到50个碳原子的未经取代的或经取代的烃氧基、酰氧基、烷氧基或烃基,其中在每种情况下非相邻碳原子可以由选自N、O、P、S的杂原子替换,其中所述基团R1、R2、R1’、R2’、R1"、R2"中的两个或三个可以彼此连接,
R3、R4、R3’、R4’、R3"各自是在每种情况下具有1到50个碳原子的未经取代的或经取代的烃基,其中在每种情况下非相邻碳原子可以经由选自N、O、P、S的杂原子或高分子量基团替换,
R4"是氢、在每种情况下具有1到49个碳原子的未经取代的或经取代的烃基,其中在每种情况下非相邻碳原子可以经由选自N、O、P、S的杂原子或高分子量基团替换,
R6是在每种情况下具有1到50个碳原子的未经取代的或经取代的烃基,其中在每种情况下非相邻碳原子可以经由选自N、O、P、S的杂原子替换,
R7、R10各自是在每种情况下具有1到10个碳原子的未经取代的或经取代的烃基,
R8是基团R6或R9,
R9是通式(6)的基团,
n、n’、n"是至少为1的整数,
x、y、y1各自是0或1,
z是至少为1的整数,
o是至少为0的整数,
p是至少为1的整数,并且
s是至少为1的整数。
通式(1)和(5)的氧杂硅杂环含有Si-O-C键,其中C原子是四取代的。
在后续步骤中,通式(4)的化合物、尤其是当R是氢或酰基时优选地与通式X-EG的端基形成化合物反应以得到通式(7)的化合物,
其中
X是OH或卤素,且
EG是烃或甲硅烷基,且
R1"、R2"、R3"、R4"、R6、R7、R10、R8、R9、n"、x、y、y1、z、o、p和s具有关于通式(4)给出的含义。
通式(4)的硅氧烷可以借助于以下工艺来制备:通过使通式(1)的氧杂硅杂环进行酸催化的开环和聚合,或使通式(1)和(5)的氧杂硅杂环与通式(3)的羟基封端的聚二甲基硅氧烷共聚,或使通式(1)和(5)的氧杂硅杂环与环状硅氧烷共聚,或使通过使硅氧烷与氧杂硅杂环反应而制备的通式(5)的遥爪化合物聚合。所提及的硅氧烷可以是被封端的,以得到通式(7)的硅氧烷。
通式(5)的氧杂硅杂环可以通过以下反应制备:使通式(2)的化合物与通式(3)的硅氧烷反应,
其中
R5是在每种情况下具有1到10个碳原子的未经取代的或经取代的烃基,并且
R1’、R2’、R3’、R4’、R6和n如关于通式(5)所定义的。
通式(1)的环状硅烷的实例是2,2,8,8-四甲基-1,7-二氧杂-6-硅杂螺[5.5]十一烷,通式(2)的化合物的一个是2-异丙氧基-2,6,6-三甲基-1,2-氧杂硅烷(2)。
其中x、y和y1=0,z=至少2并且R8具有与R9相同的含义的通式(4)和(7)的硅氧烷是含有两个烷基、在每个硅氧烷单元上具有末端双键的新颖的全烯基取代的聚硅氧烷。其实例是2,2,8,8-四甲基-1,7-二氧杂-6-硅杂螺[5.5]十一烷在紫外光照射下、使用二苯基三氟甲磺酸錪或三苯基三氟甲磺酸锍作为催化剂的聚合。
