“…The weight loss in the first-stage could be attributed to the reactions of MAA with adjacent MAA or 2-HEMA monomer unit, for which water was lost during the formation of anhydride or ester group, as pointed out in the previous works. 15,18,19 Because the ranges of thermal decompositions for poly(2-HEMA) and poly(BZMA) were 250-4308C 19 and 250-4008C, 17 respectively, the second-stage decomposition in Figure 5 was due to both 2-HEMA and BZMA segments. This explains why the weight loss of the binder containing 72% BZMA, B72M18H10, in Figure 5(a) was most obvious of the three samples over the temperature range 250-4008C.…”

Three-component acrylic copolymers used as a binder for negative-type photoresists were synthesized and characterized. First, free radical polymerization was employed to synthesize two-component binders, i.e., acrylic ester copolymers with different ratios of benzyl methacrylate (BZMA) and methacrylic acid (MAA). Thermal behavior, viscosity and molecular weight of the prepared two-component binders were studied. Then, a series of three-component binders were prepared through incorporation of another monomer, 2-hydroxyethyl methacrylate (2-HEMA). FTIR was used to examine the evolution of chemical bonds at various stages of the synthetic process. Thermal analyses, TGA and DSC, were used to evaluate the level of enhancement on thermal stabilities of the prepared three-component binders. Finally, an optimal region in the ternary composition diagram of BZMA, MAA, and 2-HEMA can be identified by comparing the results of acid value, viscosity, and molecular weight of the binder. A negative-type photoresist was prepared using an optimized composition, for which resolution of the circuit could reach the level of 6 lm.

“…It is interesting choice because its hydroxyl groups, in addition to forming hydrogen bonds will eventually form Si-O-C by condensation with silanol groups [8,9,15]. Consequently, design of efficient response active materials that are also thermally stable has been a long sought after goal [10].…”

Abstract. Poly(HEMA-BisSi) networks were prepared by using acid-catalyzed sol-gel of bis-[trimethoxysilylpropyl]amine (BisSi) and free radical polymerization of 2-hydroxyethyl methacrylate (HEMA). The thermal properties of the poly(HEMA -BisSi) networks were investigated with differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). The thermal behavior of these networks was also compared with homopolymers (The networks formed in both PHEMA and PBisSi gels were identified). The glass transition temperature (T g ) of PHEMA homopolymer was found as 103.74 °C. The thermal degradation of the poly(HEMA-BisSi) networks with different silica contents (e.g. 10, 15 and 25 wt%) were evaluated with use of DTG. It was observed that the thermal degradation temperature of poly(HEMA-BisSi) networks changed much with the BisSi content.

“…Copolymers obtained from hydrophobic and hydrophilic monomers have a great importance in various applications, such as biocompatible materials, hydrogels, and coatings [4][5][6] . The hydroxyethyl acrylate (HEA) is a soft monomer and is a bi-functional molecule since it presents an OH group and a double bond [7,8] . The glass transition temperature of the polyhydroxyethyl acrylate (PHEA) is estimated at -15 °C [7,8] .…”

SbstractNew functional polymers will be prepared using alkyd resins having high solid content (environmentally friendly) and comb-type structural morphology. Different copolymers of hydroxyethyl acrylate and methyl methacrylate (HEMMA) were synthesized by solution polymerization using azo-bis-(isobutyronitrile) (AIBN) as initiator and dimethylformamide as a solvent. The proportions utilized of AIBN were 0.5 (HEMMA1), 1.0 (HEMMA2), 1.5 (HEMMA3) and 2.0 wt. % (HEMMA4). The conversion percentage of the reaction was higher than 90%. The formation of the copolymers was evidenced by infrared analysis, hydroxyl value, and nuclear magnetic resonance. The intensity of OH group adsorption increased with the molecular weight and hydroxyl value. The polydispersity index was lower than 1.5. All copolymers exhibited a stable region on viscosity at a shear rate between 0.1 and 10 s -1 . The copolymers exhibited good thermal stability, flexibility, and adherence.
