Synthesis and nucleation ability of a novel silsesquioxane‐based β‐nucleating agent for isotactic polypropylene (iPP) are presented. A silsesquioxane cage (POSS) was octa‐functionalized with a commercially used nucleating agent, namely N2,N6‐dicyclohexylnaphthalene‐2,6‐dicarboxamide (NU‐100), and used as a carrier with the ability to promote crystallization of β‐phase in polypropylene matrix. Presented results include the synthesis route of the β‐nucleating agent (SF‐B01) and a description of its nucleation ability in iPP. The influence of SF‐B01 on iPP matrix was examined using differential scanning calorimetry, wide‐angle X‐ray scattering and static tensile tests. Investigations were complemented with polarized light optical microscopy upon non‐isothermal crystallization of composites as well as scanning electron microscopy to qualitatively assess the filler distribution. Polypropylene samples modified with different amounts of NU‐100 were used as reference. Modification carried out with both nucleating agents reveals their comparable efficiency, i.e. a structure rich in β‐phase is obtained in both cases. © 2016 Society of Chemical Industry

“…Polypropylene is a constituent of ceiling lining, shelf package, carpet, door panel, and instrument panel. The use of additives is a common way to modify polypropylene fibers to improve their properties [29]. Usually, additives such as organic pigments or flame retardants are incorporated into the polymer by physical means during fiber formation, for example [29].…”

“…The use of additives is a common way to modify polypropylene fibers to improve their properties [29]. Usually, additives such as organic pigments or flame retardants are incorporated into the polymer by physical means during fiber formation, for example [29]. Organic pigments added in polypropylene as quinacridone and phthalocyanine contain aromatic rings and thus can produce compounds such as toluene and p-xylene [29].…”

Odors from materials used in new vehicles may cause satisfaction or dissatisfaction for people. This duality is due to a stimulation caused by receptors which act differently in each individual. It is already known that odors exhaling in a vehicles interior are caused by a gaseous mixture of the various materials which are volatilized, especially with the increase of internal temperature. The components of a newly manufactured automotive vehicles interior of high surface representativeness selected in this work are eight: air conditioner, ceiling liner, shelf package, rubber mats, door panel, carpet, instrument panel, and seats, which were analyzed by gas chromatography for the identification of volatile substances. The proportion of the peak area of each compound was calculated. Gas chromatography analysis identified the main substances from materials used in interior of vehicles which contribute to the new car odor: toluene, p-xylene, ethylbenzene or benzene derivatives, except in carcass of air conditioner. Polypropylene is a constituent of these components, except the rubber mats. Carbon disulfide appeared with a significant proportion of area in rubber mats and contributed in the formation of car odors.

“…In some applications, properties of polypropylene fibers do not satisfy the special requirements and hence their modification is required. The modification is usually carried out by adding additives, which are incorporated into polymer by physical means during fiber formation 1, 2. Another possibility is the application of polypropylene copolymers or polymer blends.…”

Polypropylene/stearic acid fibers were produced in laboratory conditions from hot homogenous blends. After formation, as-spun fibers were treated in potassium hydroxide and rinsed in water. Supermolecular structure and morphology of fibers were investigated by wide-angle X-ray scattering, FTIR, and scanning electron microscopic (SEM) methods. It was stated that by fibers' formation, thermally induced phase separation takes place. Polypropylene starts to crystallize, while liquid stearic acid is expelled out and forms drops wrapped in polymer matrix. As a result of the crystallization inside fibers the structure with high content of mesophase is formed. During crystallization, interactions between stearic acid and polypropylene are observed. As a result of alkali treatment and rinsing, drops of stearic acid are partially removed. After removal of the stearic acid from the fibers, the porous structure is formed.
