共聚酰胺6/66流变性能研究

共聚酰胺6/66具有相对于传统聚酰胺6和聚酰胺66更高透明度、更好的柔韧性,因此,在抗冲击单丝、阻隔性包装薄膜和透明工程塑料件方面具有重要的应用优势。本实验采用毛细管流变仪,研究具有不同单体共聚比例共聚酰胺6/66流变性能及相关参数变化规律,并对于研究相同相对黏度共聚酰胺6/66和聚酰胺6的流变行为,发现随共聚单体的变化,聚合物的熔体表观黏度有波动,且在低剪切速率范围内相对明显,共聚第三单体的加入导致共聚体系的黏度更低。共聚比对聚合物粘流活化能的影响不大。随着共聚体系共聚比例的增加,体系非牛顿指数增加。共聚破坏了聚合物分子链结构规整性,导致共聚酰胺的表观黏度有所降低,且具有更高的非牛顿指数和更高的粘流活化能。

锦纶_6和锦纶_(66)

Development of biodegradable hot-melt adhesive based on poly-ε-caprolactone and soy protein isolate for food packaging system

A biodegradable hot-melt adhesive was developed from poly-ε-caprolactone (PCL) and soy protein isolate (SPI). PCL and SPI were mixed at varying ratios with plasticizers (coconut oil and PEG400). Thermal properties of PCL:SPI hot-melt adhesive were characterized with a differential scanning calorimeter (DSC) and softening point measurement. The surface morphology of PCL:SPI blend was examined by scanning electron microscopy (SEM). Tensile strength and elongation of PCL:SPI hot-melt adhesive films were measured using Instron testing machine. Lap shear strength of PCL:SPI hot-melt adhesives on medium density fiberboard was determined according to TAPPI UM633 method. The melting point and crystallinity of PCL in the blends decreased as the SPI content increased. The softening points of PCL:SPI hot-melt adhesive were about 59-75 °C. As the SPI concentration was increased, the tensile strength of its films decreased. The elongation of the PCL:SPI hot-melt adhesives varied with the type of plasticizer. Lap shear strength of PCL:SPI hot-melt adhesive was about 1.9 MPa.

Permeation of water through the polymeric components of boil-in-bag laminates

Diffusion coefficients and equilibrium uptake have been measured for water and 3% acetic acid in film of PETP, lldpe, nylon 6 and nylon 66, and also in some isocyanate adhesives. These materials are used in the construction of boil-in-bags for food. The three methods of measurement used were permeation from a bag, mass uptake, and the use of a novel technique using isotopically labelled water. The principal temperature of investigation has been 100 degrees C. Differences in the permeation parameters for water and 3% acetic acid were small for PETP, but surprisingly large for an inert material such as lldpe. With the nylons differences could readily be ascribed to the fact that these materials are bases. When immersed in boiling water there was no change in the degree of crystallinity of PETP, but lldpe and nylon 66 showed small increases.     

Migration of monomers and primary aromatic amines from nylon products

Migration of 2 kinds of monomer and 21 kinds of primary aromatic amines (PAAs) from 21 kinds of nylon products such as turners, ladles and wrap film were determined. Samples were classified as regards materials by mean of pyrolysis-GC/MS. One sample was classified as nylon 6, 15 samples as nylon 66 and three samples as nylon 6/66 copolymers, while two samples were laminate of nylon 6 with polyethylene or polypropylene. All of the nylon 66 samples contained a small amount of ε-caprolactam (CPL), which is the nylon 6 monomer. Migration levels of monomers and PAAs at 60°C for 30 min into 20% ethanol were measured by LC/MS/MS. CPL was detected at the level of 0.015-38 μg/mL from all samples, excluding one wrap film sample, and 1,6-hexamethylenediamine was detected at the level of 0.002-0.013 μg/mL from all nylon 66 samples and one nylon 6/66 sample. In addition, 0.006-4.3 μg/mL of 4,4'-diaminodiphenylmethane from three samples, 0.032-0.23 μg/mL of aniline from four samples, 0.001 μg/mL of 4-chloroaniline from two samples, and 0.002 μg/mL of 2-toluidine and 0.066 mg/mL of 1-naphthylamine from one sample each were detected. The migration levels at 95 or 121°C were about 3 and 10 times the 60°C levels, respectively.
