ASTM D3349-06 用炭黑着色的乙烯聚合材料吸收系数的试验方法

The absorption coefficient of polyolefin polymer pigmented with carbon black is useful to judge the degree and uniformity of dispersion of the pigment, and the adequacy of the quantitative level of pigment addition. These factors are used to predict the performance of the polymer material in response to prolonged exposure to ultraviolet light as evidenced by minimal changes in specific properties. Note 18212;This test method was developed to evaluate ethylene polymer materials pigmented with small particle size carbon blacks suitable for UV protection. It is not known how accurate and reproducible the test would be with larger particle size blacks.1.1 This test method measures the amount of light transmitted through a film of carbon black pigmented ethylene polymer.1.2 After calculation of the amount of light and film thickness, an absorption coefficient is calculated.1.3 Whenever two sets of values are presented, in different units, the values in the first set are the standard, while those in parentheses are for information only.This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

The MW averages and the MWD are important characteristics of a resin. They may be used for a variety of correlations for fundamental studies, processing, or product applications. The MW and MWD values may also be used for production quality control of resins. Limitations8212;Comparison of SEC molecular weight values should be made only if the data were obtained under identical chromatographic conditions.1.1 This practice covers the determination of apparent molecular weight (MW) averages and molecular weight distributions (MWD) for THF-soluble hydrocarbon and terpene resins by size-exclusion chromatography (SEC). This technique is not absolute; it requires calibration with standards of known molecular weight. This practice is applicable to resins containing molecular-weight components that have elution volumes falling within the elution volume range defined by polystyrene standards.Note 1SEC is also known as gel permeation chromatography (GPC).1.2 SEC systems employ low-volume liquid chromatography components and columns packed with relatively small (generally 3 to 20 m) microporous particles. High-performance liquid chromatography instrumentation and automated data handling systems for data acquisition and processing are also required.1.3 The values stated in SI units are to be regarded as the standard.

ASTM D5492-06 丙烯塑料中二甲苯可溶物标准试验方法

The results of this test provide a relative measure of the total soluble fraction of polypropylene homopolymers and copolymers. The soluble fraction can be approximately correlated to the amorphous fraction in the polypropylene. Xylene is widely used for determining the soluble fraction in polypropylene. Xylene is more specific to the atactic fraction than other solvents. The concentration of a soluble fraction obtained with a specific solvent has been found to relate closely to the performance characteristics of a product in certain applications, for example film and fiber. Data obtained by one solvent and at one precipitation time cannot be compared with data obtained by another solvent or precipitation time, respectively.1.1 This test method is to be used for determining the 25176;C xylene-soluble fraction of polypropylene homopolymers and copolymers.1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

ASTM D4875-05 聚氨基甲酸乙酯原材料的标准试验方法:聚醚多元醇的聚合环氧乙烷含量的测定

Measurements of EO content correlate with polyol reactivity (as related to primary hydroxyl content), linearity of foam rise, and the hydrophilicity of the polyol and final product. Statistical data suggest that the 13C NMR test method is the preferred method for measuring low levels (less than 10 %) of polymerized EO in polyols. The 1H and 13C NMR test methods give different results which are highly correlated. The equation of the linear regression is: The standard deviation of the regression is 0.49 and the multiple R-square is 0.9990.1.1 Test Method A8212;Proton Nuclear Magnetic Resonance Spectroscopy (1H NMR) measures polymerized ethylene oxide (EO) in ethylene oxide-propylene oxide polyethers used in flexible urethane foams and nonfoams. It is suitable for diols made from the commonly used initators and containing EO percentages above five. For triols initiated with glycerin and trimethylol propane, an uncorrected EO value is obtained since both initiators have protons that contribute to the EO measurement.1.2 Test Method B8212;Carbon-13 Nuclear Magnetic Resonance Spectroscopy (13C NMR) measures the polymerized EO content of ethylene oxide-propylene oxide polyethers used in flexible urethane foams and nonfoams.
