Samples with a higher molecular weight of PEO than PMMA are water soluble. Water Solubility alcohols and aliphatic hydrocarbons: insoluble | Soluble in tetrahydrofuran, toluene, cyclohexanone, ethyl acetate and chloroform. According to their behaviour in solution, polymers containing PEO and PMMA are regarded as non-ionic amphiphiles. Poly(hexyl methacrylate) solution average M w ~400,000 by GPC, in toluene Synonym: Hexyl methacrylate homopolymer, Poly(1-hexyl methacrylate) CAS Number 25087-17-6. In the case of using the mixture of MIBK-xylene, the solubility is the average of those of the pure solvents [17]. Accordingly, MMA should be soluble in toluene/acetone 3:1 but not in 100% toluene. Solubility Grades (% Toluene) of Polymers at 10% solids with Hildebrand Values of the Corresponding Toluene-Dodecane blends; Polymer Solubility Grade ∂/MPa ½; Poly vinyl acetate 89 18.05 Poly methyl methacrylate 87 18.00 Acryloid® B-72 (Rohm and Haas) 80 17.84 Poly n-butyl methacrylate 25 16.58 Poly isobutyl methacrylate 23 1,2 Moreover, scCO 2 has an easily attainable critical point (31.0 °C, 73.8 bar), which is advantageous from an energetic perspective. Linear Formula (C 10 H 18 O 2) n. MDL number MFCD00084433. The unperturbed dimension K θ was calculated using three different procedures. Cyanoacrylate and acrylic [PMMA, MMA, etc] based polymers can get good bonding at the molecular level. [ABS, PVC, HIPS] => Acetone and M ethyl E thyl K etone [MEK aka 2-Butanone] will dissolve both ABS and PVC and chemically rebuild the joint in a less ordered manner as the solvents dries. Table 2 gives the Solubility Grades of several polymers, along with the corresponding Hildebrand number (SI) of the toluene-dodecane solution. PubChem Substance ID 24850979. Fig. However, it is not just the type of solvent/polymer that influences the process. NACRES NA.23 1. Table 2. Introduction Supercritical carbon dioxide (scCO 2) is a benign solvent (nontoxic, non-flammable, and inert), that has emerged as a potential replacement for organic solvents. The higher the percentage of toluene in the blend, the "stronger" is the solvent strength of the blend; the Solubility Grade is therefore the mildest blend that can be used to dissolve the polymer. At 35°C, DMSO is a theta solvent for PMMA, and it becomes a good solvent as the temperature increases. Next: Part 7 - … Example of a retention diagram for dichloromethane-PMMA-co BMA system above Tg. Figure 7 Hansen graph of solubility areas for polyvinyl acetate (PVA), poly vinyl butyral (PVB) and poly vinyl chloride (PVC). The copolymers are soluble in toluene, acetone, tetraline, tetrahydrofuran (THF), chloroform and methyl ethyl ketone (MEK). However, the butyl methacrylate resins are readily soluble in VM & p naphtha and some grades of mineral spirits. PMMA prepared by free radical polymerization is amorphous and is therefore soluble in solvents with similar solubility parameters such as benzene, toluene, chloroform, methylene chloride, esters, ethyl acetate, and amyl acetate. It is of great interest that the THF‐insoluble poly(MMA) was soluble in benzene and toluene, but insoluble in polar solvents, such as ethyl acetate, acetone, methyl ethyl ketone, dimethylformamide, and dimethylsulfoxide. Solutions of "Elvacite" 2044, 2045, and 2046 in these low-cost hydrocarbon solvents have workable viscosities even at solids contents as high as 30-40% by weight. The separated THF‐insoluble part differed significantly from the usual radical poly(MMA) in solubility characters. This type of graph uses only two of the three Hansen parameters. Insoluble in water, alcohols and aliphatic hydrocarbons. MIBK has no a good solubility parameter for PMMA - 17.2 (J 1/2 cm-3/2), which provides a difference greater than 1.5.
