Partial molar heats of mixing of small molecules with polymers by gas chromatography: Partial molar heats of mixing of small molecules with polymers by gas chromatography. DiPaola-Baranyi, G.; Braun, J. M.; Guillet, J. E. (Dep. Chem., Univ. Toronto, Toronto, Ont., Can.). Macromolecules, 11(1), 224-7 (English) 1978. CODEN: MAMOBX. ISSN: 0024-9297. DOCUMENT TYPE: Journal CA Section: 35 (Synthetic High Polymers) Partial molar heats of mixing (DH1￥) of normal C8-14 alkanes were of the order of few hundred cal/mol in polyethylene [9002-88-4], polypropylene [9003-07-0], and poly-1-butene [9003-28-5]. Polymers contg. minor amts. of polar groups, such as ethylene-vinyl acetate polymer [24937-78-8] of vinyl acetate content 18% and carbon monoxide-ethylene copolymer [25052-62-4] of CO content 10.5% showed minor effects on DH1￥. In more polar polymers, such as polystyrene [9003-53-6], poly(Me acrylate) [9003-21-8], and PVC [9002-86-2], or poly(N-isopropylacrylamide) [25189-55-3], (with BuOH [71-36-3] solute), DH1￥ ranged from 1 to 4 kcal/mol. The DH1￥ were detd. by gas chromatog.

Poly(N-isopropyl acrylamide) adhesion promoting modifiers for cellulose ester lacquer coatings: Poly(N-isopropyl acrylamide) adhesion promoting modifiers for cellulose ester lacquer coatings. Anon. (Engl.). Res. Discl., 158, 18 (English) 1977. CODEN: RSDSBB. DOCUMENT TYPE: Journal CA Section: 42 (Coatings, Inks, and Related Products) Poly(N-isopropylacrylamide) (I) [25189-55-3] was useful as an adhesion promoter for cellulose [9004-34-6] ester coatings, esp. on wood substrates. The optimum concn. of I was .apprx.20% and inherent viscosity .apprx.0.6. The cellulose ester had an optimum seconds viscosity 0.1-20 (ASTM D-817-65), 2-30% acetyl content and 15-50% butyryl content.
