Abstract: 본 발명은 암모니아 또는 아민을 이용하여 팽윤시킨 셀룰로오스 펄프를 압출기 또는 혼련기 내에서 NMMO 용매에 직접 용해시키는 것이 특징인, 셀룰로오스 섬유 및 필름을 제조하는 데에 사용될 수 있는 고균질의 셀룰로오스 용액의 제조 방법에 관한 것이다. 본 발명에 따르면, 용매의 침투가 용이한 팽윤된 셀룰로오스 펄프를 사용하기 때문에 압출기 내에서 별도의 팽윤 과정 없이 바로 균질의 셀룰로오스 용액을 제조할 수 있다. 따라서, 본 발명의 셀룰로오스 용액의 제조 방법은 종래의 방법보다 공정이 간단하고, 단시간에 고균질의 용액을 제조할 수 있다.

Abstract: Obtaining a PAN/H2O mixture of gel crystal, it is extruded simply through a die, an extrusion which has a collection of tiny fibers in its inner structure is produced, and this extrusion is opened and a new 3rd generation acrylic short fiber is obtained. In this process, a gel crystal is formed, which has the characteristics of spontaneous molecular orientation. So, without spinning nor drawing process, a fiber containing far better molecular orientation than the previous high drawn fiber is produced.

Abstract: The PVC structured foam is prepd. by the single extruding vinyl chloride resin with 3-10 phr of lower molecular polar plasticizer and 4-20 phr of the anti- impact modifier. The obtd. hard PVC structured foam has a thick non-foamed surface layer, good transparence, scratch resistance and impact resistance. Pref. the lower polar plasticizer is phthalate gp., cebacate gp. or adiphate gp., and the anti-impact modifier is methacrylic acid methyl-butadience- styrene copolymer or vinyl acetate-butadience-styrene copolymer.

Abstract: The process for making quinoline-imide polymer includes the steps of ;(a) making diamine by dissolving aromatic quinoline diamine in organic solvent such as N-NMP, N,N-DMAc, N,N-DMP or DMSO; (b) polymerizing by adding aromatic 4-basic oxide anhydride such as PMDA, BPDA, BTDA, ODPA, DSDA, 6FDA or NTDA to it; (c) obtaining polyquinoline amic acid film from it; (d) treaing it with heat. The viscosity of the polymer is above 0.1 dl/g when measuring at 30 deg.C with 0.5% sulfuric acid.
