Embodiment approach

[0042] According to an exemplary embodiment of the present invention, the condensed aromatic compound includes a dioxoanthracene derivative represented by the following general formula:

[0043] [general formula]

[0044]

[0045] Among them, R 1 to R 8 Each of is independently a hydrogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group, a substituted or unsubstituted heterocyclic group, or is capable of forming a hydrogen bond with the aromatic polyamide functional groups.

[0046] Preferably, R 1 to R 8 At least one of them is a functional group capable of forming a hydrogen bond with the aromatic polyamide, and the functional group is selected from -COOH, -NH 2 , -OH, -SO 3 H, -SO 2 NH 2 ,-CONH 2 , -SH and aromatic or aliphatic derivatives containing -O-, -NH- or -S-.

[0047] Since the dioxanthracene derivative only contains 3 fused rings, it is beneficial to interact with the aramid instead of itself, and it is easy ...

Embodiment 1

[0070] CaCl 2 Adding N-methyl-2-pyrrolidone (NMP) to prepare a polymerization solvent; dissolving p-phenylenediamine in the polymerization solvent to prepare a mixed solution.

[0071] Then, stir the mixed solution, divide the terephthaloyl chloride with the molar equimolarity of the above-mentioned p-phenylenediamine into 2 equal parts and add it into the mixed solution to prepare poly(p-phenylenediamine terephthalamide) polymer . Then, water and NaOH were added to the polymer solution containing the polymer to neutralize the acid. Then, the polymer is ground, the polymerization solvent contained in the aramid polymer is extracted with water, and the residue is dehydrated and dried, yielding an aramid as a final product.

[0072] N-(4-amino-3-methoxy-9,10-dioxoanthracene-1-yl)-4-methylbenzenesulfonamide was added to the aromatic polyamide thus prepared to prepare the aromatic polyamide Amide composition. The content of N-(4-amino-3-methoxy-9,10-dioxoanthracen-1-yl)-4-meth...

Embodiment 2

[0075] In addition to using 9-hydroxyl anthracene instead of N-(4-amino-3-methoxy-9,10-dioxoanthracene-1-yl)-4-methylbenzenesulfonamide, with the same method as in Example 1 Aramid fibers were prepared in the same manner.

Abstract

Disclosed is an aramid product in which the number of defects present in noncrystalline regions is considerably reduced and a composition for aramid for producing the same. The composition contains aromatic polyamide and a fused aromatic compound, wherein the content of the fused aromatic compound is 0.01 to 10 parts by weight, based on 100 parts by weight of the aromatic polyamide.

Description

technical field [0001] The present invention relates to an aromatic polyamide composition and an aromatic polyamide product manufactured using the composition. Background technique [0002] In general, wholly aromatic polyamides (also referred to as "aromatic polyamides") include para-type wholly aromatic polyamides having a structure in which benzene rings are linearly linked through amide groups (CONH), and para-type wholly aromatic polyamides not having this structure The meta-type fully aryl polyamide. [0003] In particular, aramid fibers prepared using para-type wholly aramids have excellent properties such as high strength, high modulus, low shrinkage, and especially exceptionally high strength (using filaments about 5 mm thick capable of lifting a 2-ton car), and is therefore used in bulletproof applications as well as in a variety of applications in high-tech industries such as aerospace. In addition, aramid fibers are not carbonized at 500° C. or higher, so they ...
