Physicochemical Characterization of Polyvinyl Chloride). III. Stereoregularity
Autor: T. S. Wang, M. D. Baijal
Publikováno v: Journal of Macromolecular Science: Part A - Chemistry. 5:1141-1148
Tacticity of poly(vinyl chloride) (PVC) prepared in the 55 to 160°C range has been determined by the temperature dependence of the intensity ratios of the IR absorption bands at 1434 and 1428 cm−1. Syndiotactic content of these materials varied fr

Molecular heterogeneity characterization in polyglycols
Autor: M. D. Baijal, L. P. Blanchard
Publikováno v: Journal of Applied Polymer Science. 12:169-174
This paper deals with polydispersity coefficient characterization in poly(propylene glycols) (PPG 425, 750, 1025, 1200, and 2025) and poly(ethylene glycols) (PEG 200, 600, and 1000). The methods used involved ratio of 50% solution to intrinsic viscos

Physicochemical Characterization of Poly(vinyl chloride). II. Molecular Weight Distributions
Autor: M. D. Baijal
Publikováno v: Journal of Macromolecular Science: Part A - Chemistry. 2:1055-1063
Molecular weight distributions in poly(vinyl chloride) resins have been determined from simple viscosity measurements. Ratio of 11% solution viscosity to intrinsic viscosity yielded a figure which has been correlated with molecular weight distributio

Kinetic aspects of the copolymerization of tetrahydrofuran with propylene oxide. Part II
Autor: M. D. Baijal, L. P. Blanchard
Publikováno v: Journal of Polymer Science Part C: Polymer Symposia. 23:157-167
The cationic copolymerization of tetrahydrofuran with propylene oxide was carried out in the presence of boron fluoride etherate, 1,2-propanediol, and ethylene chloride, used as catalyst–cocatalyst–solvent system. Reactions were carried out in th

KINETIC ASPECTS OF THE COPOLYMERIZATION OF TETRAHYDROFURAN WITH PROPYLENE OXIDE. I
Autor: M. D. Baijal, J. Singh, L. P. Blanchard
Publikováno v: Canadian Journal of Chemistry. 44:2679-2689
Tetrahydrofuran and propylene oxide were copolymerized in the presence of the catalyst boron fluoride ethyl ether, and various co-catalysts, such as 1,2-propanediol, 1,3-propanediol, and 1,4-butanediol. Ethylene chloride was used as a solvent and as

Physico-chemical characterization of poly(vinyl chloride). I. Solution properties
Autor: K. M. Kauppila, M. D. Baijal
Publikováno v: Polymer Engineering and Science. 11:182-186
Poly(vinyl chloride) was fractionated and its solution properties were studied. Calibration of the gel permeation chromatograph was carried out using poly(vinyl chloride) and polystyrene. Empirical correlations were established for the calibration pl
