The copolymers are soluble in toluene, acetone, tetraline, tetrahydrofuran (THF), chloroform and methyl ethyl ketone (MEK). This type of graph uses only two of the three Hansen parameters. Insoluble in water, alcohols and aliphatic hydrocarbons. NACRES NA.23 According to their behaviour in solution, polymers containing PEO and PMMA are regarded as non-ionic amphiphiles. 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. At 35°C, DMSO is a theta solvent for PMMA, and it becomes a good solvent as the temperature increases. 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. 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. However, the butyl methacrylate resins are readily soluble in VM & p naphtha and some grades of mineral spirits. Example of a retention diagram for dichloromethane-PMMA-co BMA system above Tg. The separated THF‐insoluble part differed significantly from the usual radical poly(MMA) in solubility characters. [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. Linear Formula (C 10 H 18 O 2) n. MDL number MFCD00084433. 1. Accordingly, MMA should be soluble in toluene/acetone 3:1 but not in 100% toluene. Table 2. 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. Samples with a higher molecular weight of PEO than PMMA are water soluble. 1,2 Moreover, scCO 2 has an easily attainable critical point (31.0 °C, 73.8 bar), which is advantageous from an energetic perspective. Table 2 gives the Solubility Grades of several polymers, along with the corresponding Hildebrand number (SI) of the toluene-dodecane solution. Figure 7 Hansen graph of solubility areas for polyvinyl acetate (PVA), poly vinyl butyral (PVB) and poly vinyl chloride (PVC). However, it is not just the type of solvent/polymer that influences the process. 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. Next: Part 7 - … In the case of using the mixture of MIBK-xylene, the solubility is the average of those of the pure solvents [17]. PubChem Substance ID 24850979. Cyanoacrylate and acrylic [PMMA, MMA, etc] based polymers can get good bonding at the molecular level. 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. Water Solubility alcohols and aliphatic hydrocarbons: insoluble | Soluble in tetrahydrofuran, toluene, cyclohexanone, ethyl acetate and chloroform. 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.
