Description
本發明係關於一種雙胺雙羧鹽、共聚物及其製備方法。 The present invention relates to a bisamine dicarboxylate, a copolymer and a process for the preparation thereof.
目前尼龍6(nylon 6)纖維已廣泛應用於日常生活中,如衣著、傢飾用品、或其他領域等。然而,與尼龍66(nylon 66)比較,尼龍6的熔點、軟化點、耐熱性、及機械強度都比尼龍66低。這些不利的物性長期限制了尼龍6下游應用產品的開發範圍。業界嘗試以化學合成手段生產差異化尼龍6的技術,其期提高尼龍6的附加價值。然而,在目前尼龍6的改質技術上,仍無法得到具有高均勻性序列分佈、及高熔點兩種物性的尼龍6產品。此外,尼龍6改質產品之熔點亦不能高於其裂解點,否則不易進行後續加工製程。 At present, nylon 6 (nylon 6) fiber has been widely used in daily life, such as clothing, home furnishings, or other fields. However, compared to nylon 66 (nylon 66), nylon 6 has a lower melting point, softening point, heat resistance, and mechanical strength than nylon 66. These unfavorable physical properties have long limited the development of nylon 6 downstream applications.

However, in the current upgrading technology of nylon 6, it is still impossible to obtain a nylon 6 product having a high uniformity sequence distribution and a high melting point physical property. In addition, the melting point of nylon 6 modified product can not be higher than its cracking point, otherwise it is not easy to carry out subsequent processing.

比較實施例3 Comparative Example 3
依據文獻(Rwei,S.P.et al.,Thermochimica Acta,555,37-45,2013)所述之一般尼龍共聚物的合成方法,將乙二胺(ethylenediamine、EDA)、間苯二甲酸二甲酯(dimethyl isophthalate、DMI)、以及己二酸(adipic acid、AA)(莫耳比例為1:1:2)進行熔融共聚合反應,得到共聚物7。 According to the synthesis method of a general nylon copolymer described in the literature (Rwei, SP et al., Thermochimica Acta, 555, 37-45, 2013), ethylenediamine (EDA), dimethyl isophthalate ( The dimethyl isophthalate, DMI), and adipic acid (AA) (molar ratio: 1:1:2) were subjected to melt copolymerization to obtain a copolymer 7.
以示差掃描熱量計(differential scanning calorimeter)測量共聚物7,得知其熔融溫度(Tm)有多個明顯的峰值,介於196℃至240℃之間,以及相對黏度(R.V.)為2.1。 The copolymer 7 was measured by a differential scanning calorimeter, and it was found that its melting temperature (Tm) had a plurality of distinct peaks, ranging from 196 ° C to 240 ° C, and a relative viscosity (R.V.) of 2.1.
由表1可得知,由於共聚物6(比較實施例2)係使用較具剛性的對苯二甲酸二甲酯(dimethyl teraphthalate、DMT)作為反應起始物(且未添加間苯二甲酸二甲酯),因此與本申請案所述共聚物1相比(實施例6、使用間苯二甲酸二甲酯(dimethyl isophthalate、DMI)作為反應起始物),導致產物熔點高於其裂解溫度,無法進行後續的加工製程。共聚物7(比較實施例3)為一般常用的隨機聚合(random polymerization)的製程(使用EDA、DMI、AA三種單體進行共聚合反應),此製程會導致共聚物內含有許多混亂的各種不同組成的聚合物區塊的生成(random copolymer),如此各單體成份於共聚物內的序列分佈不佳,導致結晶性不佳,從而降低了共聚合產物的熔點、強度、物性穩定性等。反觀共聚物1-3(實施例6-8),其先將EDA(或BDA)與DMI合成為二胺型單體,此單體再與二羧酸型單體(AA或SA)進行共聚合反應,如此可得到序列分佈最優的交錯型(alternative)聚合物,提高共聚物的對稱性、高序列分佈性、以及高熔點等物性。此外,由於使用具有二取代官能基之間位苯基化合物作為反應單體,如此一來可降低共聚物的剛 性,避免共聚物的熔點高於其裂解溫度(>280℃),解決使用具有二取代官能基之對位苯基化合物作為起始物所得之共聚物無法加工的問題。另一方面,本申請案也可藉由加入二取代官能基之間位苯基化合物作為反應單體,與二取代官能基之對位苯基化合物混合,用來調控所得共聚物的熔點。由本申請案共聚物4-5(實施例9-10)可得知,增加二取代官能基之間位苯基化合物與二取代官能基之對位苯基化合物的莫耳比,可降低所得共聚物的熔點,避免共聚物的熔點高於其裂解溫度。 As can be seen from Table 1, since the copolymer 6 (Comparative Example 2) uses relatively rigid dimethyl phthalate (DMT) as a reaction starting material (and no isophthalic acid is added) Methyl ester), thus compared to copolymer 1 of the present application (Example 6, using dimethyl isophthalate (DMI) as the starting material for the reaction), resulting in a product melting point above its pyrolysis temperature , the subsequent processing can not be carried out. Copolymer 7 (Comparative Example 3) is a commonly used random polymerization process (copolymerization using three monomers of EDA, DMI, AA), which causes a lot of confusion in the copolymer. The formation of a polymer block, such that the sequence distribution of each monomer component in the copolymer is poor, resulting in poor crystallinity, thereby reducing the melting point, strength, physical stability and the like of the copolymerized product. In contrast, copolymers 1-3 (Examples 6-8), which first synthesize EDA (or BDA) and DMI into diamine monomers, which are then co-linked with dicarboxylic acid monomers (AA or SA). The polymerization reaction can obtain an alternative polymer with optimal sequence distribution, and improve the symmetry, high sequence distribution, and high melting point physical properties of the copolymer. In addition, since a phenyl compound having a disubstituted functional group is used as a reactive monomer, the copolymer can be reduced. The problem is that the melting point of the copolymer is higher than the cracking temperature (>280 ° C), and the problem that the copolymer obtained by using the para-phenyl compound having a disubstituted functional group as a starting material cannot be processed is solved. On the other hand, the present application can also be used to adjust the melting point of the obtained copolymer by adding a phenyl compound as a reactive monomer between the disubstituted functional groups and a para-phenyl compound of the disubstituted functional group. It is known from the copolymers 4-5 (Examples 9-10) of the present application that increasing the molar ratio of the phenyl compound of the disubstituted functional group to the para-phenyl compound of the disubstituted functional group can reduce the copolymerization obtained. The melting point of the substance, to avoid the melting point of the copolymer is higher than its cracking temperature.
