Abstract
本公开的实施方式涉及官能化的低聚物。例如,官能化的低聚物可以由式(I)表示:(式I)其中R1为式II的结构:(式II)且R2具有式-CXHYO-,其中n是值为2至6的整数,m是值为2至10的整数,X独立地为值为1至12的整数,Y是值为2至24的整数。
Description
技术领域
本公开的实施方式涉及官能化的低聚物,更特别地,实施方式涉及可用于形成开孔泡沫体的组合物的官能化的低聚物。
背景技术
泡沫体是其中气体分散在液体材料、固体材料、或凝胶材料中的分散体。固体泡沫体包括闭孔泡沫体和开孔泡沫体。
在闭孔泡沫体中,气体形成离散的孔穴,其中离散的孔穴完全由固体材料包围。闭合的孔可以称为非相互连通的。因为离散的孔穴完全由固体材料包围,因此闭合的孔形成硬质材料,例如,硬质泡沫体。另外,闭合的孔有助于防止气体或液体穿过闭孔泡沫体。闭孔泡沫体用于多种应用,尤其例如热绝缘,蒸气绝缘,液体绝缘,接缝填充应用,和冲击保护应用等。
与闭孔泡沫体相反,在开孔泡沫体中,气体孔穴相互连接。开孔可以称为相互连通的。因为开孔泡沫体的气体孔穴不完全由固体材料包围,因此开孔可以形成软质材料,例如,软质泡沫体或粘弹性泡沫体。开孔泡沫体用于多种应用,尤其例如一些绝缘应用,包装应用,汽车装饰,过滤器,和声学应用等。
发明内容
本公开提供式(I)的官能化的低聚物:
(式I)
其中R1为式II的结构:
(式II)
并且R2具有式-CXHYO-,其中n是值为2至6的整数,m是值为2至10的整数,X独立地为值为1至12的整数,Y是值为2至24的整数。R3可以是脂族化合物,芳族化合物,或胺化合物。
本公开提供形成开孔泡沫体的组合物。形成开孔泡沫体的组合物可以包括本申请提供的官能化的低聚物以及多官能迈克尔(Michael)受体。
上述本公开的内容并未意在描述每种公开的实施方式或本公开的每种实践。以下说明书更特别地例证说明性的实施方式。在整个申请的几个地方,通过实施例的列举提供了指导,该实施例可以按各种组合使用。在每种情况中,所述清单仅用作代表性组,不应将其理解为详尽清单。
具体实施方式
本申请描述了官能化的低聚物。这些官能化的低聚物可以包含在可得到开孔泡沫体的形成开孔泡沫体的组合物中。不同于一些其它泡沫体例如聚氨酯泡沫体,有利地,本申请公开的开孔泡沫体不使用异氰酸酯,异氰酸酯可能是一些应用所不期望的。本申请公开的开孔泡沫体有利地为具有下述性质的泡沫体,所述性质尤其例如为泡沫体密度等,这些性质是一些应用所期望的。本申请公开的开孔泡沫体可以用于多种应用,尤其例如一些绝缘应用,包装应用,汽车装饰应用,过滤器应用,和声学应用等。
本申请所述的官能化的低聚物可以由以下式I表示:
(式I)。
R1可以由以下式II表示:
(式II)
且R2具有式-CXHYO-。如本申请使用,n是值为2至6的整数,m是值为3至10的整数,X是值为1至12的整数,Y是值为2至24的整数。R3可以是脂族化合物,芳族化合物,或胺化合物。应该知道,式(I)官能化的低聚物混合物的n、m、X和Y数值可以是本申请提供的n、m、X和Y的给定范围的有理数。式II中的波浪键表示在该点的具有不同可能性的立体化学的混合物。
例如,由式I表示的官能化的低聚物的R1可以具有式III的结构,
(式III)
例如,其中n的值为3,m的值为2或3,a的值为2或3,X的值为2,Y的值为4。
例如,由式I表示的官能化的低聚物的R1可以具有式IV的结构,
(式IV)
例如,其中n的值为2,m的值为3至4,b的值为3至4,X的值为2,Y的值为4。
也可以称为乙酰乙酸酯低聚物和/或迈克尔供体的官能化的低聚物可以由化学反应例如通过酯交换反应形成。酯交换反应可以包括多元醇和酯。
如本申请使用,"多元醇"是指平均每分子具有大于1.0个羟基的有机分子。可用于形成官能化的低聚物的多种多元醇是可商购的,尤其是,例如IP-625(乙氧基化甘油),和IP-9001(乙氧基化对苯二甲酸),两者都购自DowChemical Company,以及其它可商购的多元醇。可用于形成官能化的低聚物的多种多元醇可以通过化学反应例如烷氧基化反应形成。烷氧基化反应可以包括使引发剂(例如水、乙二醇、或丙二醇)与环氧烷烃(例如环氧乙烷、环氧丙烷、或环氧丁烷)在催化剂的存在下反应。用于形成官能化的低聚物的多元醇的实例包括但不限于,乙氧基化甘油,乙氧基化对苯二甲酸,聚(四亚甲基二醇),聚己酸内酯,聚(环氧丁烷),聚羟基异丁烯(Krasol多元醇),蓖麻油(蓖麻酸的甘油三酯),加氢甲酰化以及还原的种子油的多元醇,乙氧基化芳族酚,对苯二酚二醚乙醇(hydroquinone dietherethanol),及其组合,以及其它多元醇。
