“…However, results reported by others shows that the addition of 10 wt% Mg(OH) 2 leads to a slight decrease of T g value (4°C) [26]. It is well known that the effects of the presence of fillers on the T g of polymer matrix is related to the rigid phase reinforcement and crosslinking network of the thermosetting polymer matrix [27][28][29]. Unlike the halogen-free reactive flame retardant, DOPO [30], the addition of brucites has negligible influence on the crosslinking networks of epoxy resin.…”

“…Renewable substances proposed for the synthesis of polymers are, for example, vegetable oils (e.g., linseed oil, sunflower oil, palm oil, cotton oil, soybean oil, tung oil, cashew nut oil [5][6][7][8]), glycerol and its derivatives [9,10], terpenes [11] and rosin [12,13]. The bio-based components, which can be used as a polyols in the synthesis of polyurethanes, are, for example, castor oil [14], polyricinoleate diol [15], hydroxylated soybean oil [6,16], hydroxylated hemp seed oil [17] and polyglycerols [18]. Bio-based trends are also visible in the synthesis of isocyantes [19].…”

The main aim of this work was to obtain poly(ether-urethane)s using tri-functional polyoxyalkylene polyol (Rokopol G1000), which introducing the chemical cross-links into the structure of polyurethanes. Poly(etherurethane)s were prepared using two-step method, called prepolymer method, which involves in the first step the reaction of 4,4 0 -diphenylmethane diisocyanate (MDI) and tri-functional polypropylene glycol glycerol triether polyol. In the second step, prepolymer chains were extended by using: 1,6-hexanediol, 1,4-butanediol in the mixture with poly(ethylene glycol) and poly(ethylene glycol). The prepolymer chains extending was realized at three different molar ratios of NCO groups (presented in prepolymer) to OH groups (presented in chain extender), i.e., 0.95, 1.00 or 1.05. The influence of chain extender type on the chemical structure, selected mechanical properties and thermomechanical properties of the obtained poly(ether-urethane)s was investigated. The results showed that applying different types of chain extenders results in obtaining materials with diversified mechanical properties, but very similar thermal stability. The performance of obtained poly(etherurethane)s is mostly affected by the chemical cross-links, which were introduced into soft segments by tri-functional polyetherol.

As a reinforcing filler, nano‐silica was modified using silane coupling agents (KH560 and KH570). The effects of nano‐silica loadings on the morphology, mechanical and thermal properties of castor oil‐based PU nanocomposites were studied. Scanning electron microscopy demonstrated the relatively homogeneous dispersion of nano‐silica in the PU matrix. After the addition of different nano‐silica, a significant nano‐silica reinforcement effect on castor oil‐based PU matrix was found. The tensile strength and Young's modulus of the PU nanocomposites were increased with the increment of different nano‐silica content. When compared with neat PU, PU/silica nanocomposites with 12 wt% SiO2, KH560‐SiO2 and KH570‐SiO2 loading exhibited 222, 230, and 87% improvement in tensile strength, and 182, 182, and 88% increment in Young's modulus, respectively. Furthermore, the thermal stability of PU nanocomposites was slightly improved with the incorporation of KH570‐SiO2. At 12% SiO2, KH560‐SiO2, and KH570‐SiO2 loading, the residue of PU nanocomposites at 600°C were increased from 3.4 to 12.7, 13.1, and 10.6%, respectively. POLYM.
