Abstract: Proposed are a core-satellite micelle containing a tetra-block copolymer and a preparation method thereof. The core-satellite micelle includes a core, a shell surrounding the core, and a plurality of satellite domains positioned inside the shell. The core-satellite micelle contains a tetra-block copolymer represented by Structural Formula 1 below. The shell includes a first-monomer first block A1 and a first-monomer second block A2, and the satellite domain includes a second-monomer first block B1 and a second-monomer second block B2. The core-satellite micelle is foiled through self-assembly of the tetra-block copolymer, thereby having a larger interfacial contact area than existing block-copolymer micelles. Therefore, the core-satellite micelle can be used in next-generation nanotechnology applications such as drug delivery systems, porous catalyst materials, and sensors.
A1-B1-A2-B2 [Structural Formula 1]
In Structural Formula 1,
A1 is a first-monomer first block,
B1 is a second-monomer first block,
A2 is a first-monomer second block, and
B2 is a second-monomer second block.-

Abstract: The present invention relates to a process for producing polymer microparticles laden with at least one aroma chemical, which comprises i. dissolving the at least one aroma chemical and an organic polymer composition, which contains at least one polyester as a main constituent, in a volatile organic solvent having a boiling point lower than the boiling point of the aroma chemical and having a solubility in water of at most 100 g/L at 20° C. and 1013 mbar, whereby a solution of the aroma chemical and the organic polymer composition is obtained; ii. emulsifying the solution obtained in step i. in an aqueous medium containing at least one dispersant; iii. removing the volatile organic solvent from the emulsion by evaporation at a temperature of below 80° C. and at a pressure below atmospheric pressure, whereby an aqueous suspension of the laden polymer microparticles is obtained. The present invention also relates to microparticles laden with an aroma chemical, obtainable by the process described herein and to products containing the microparticle composition. The compositions are useful as additives for imparting a scent or flavour to a product. The compositions allow for controlled release of the aroma chemicals.

Abstract: It is provided a composition comprising a hyperbranched polyester polyol derivative and a small molecule comprising at least one cyclic amine. The hyperbranched polyester polyol derivative is obtainable by a method comprising the following steps: a) reacting only glycidol and ε-caprolactone at a temperature lying in a range of between 40° C. and 140° C. to obtain a hyperbranched polyester polyol derivative in which caprolactone residues and glycerol residues are randomly arranged; b) reacting the hyperbranched polyester polyol derivative of step a) with a sulfation reagent to obtain a sulfated hyperbranched polyester polyol as hyperbranched polyester polyol derivative.

Abstract: The present invention provides polymersomes comprising amphiphilic block-copolymers and their use to quantify ammonia in samples (e.g., body fluid samples). More particularly, it provides a polymersome comprising (a) a membrane, which comprises a block copolymer of poly(styrene) (PS) and poly(ethylene oxide) (PEO), wherein the PS/PEO molecular weight ratio is higher than 1.0 and lower than 4.0; and (b) a core which encloses an acid and at least one pH-sensitive dye. Compositions, strips and kits comprising the polymersomes are also provided along with methods of quantifying ammonia in a sample using the polymersomes, compositions and kit.

Abstract: The invention relates to a method of making hybrid organic-inorganic core-shell nano-particles, comprising the steps of a) providing colloidal organic particles comprising a synthetic polyampholyte as a template; b) adding at least one inorganic oxide precursor; and c) forming a shell layer from the precursor on the template to result in core-shell nano-particles. With this method it is possible to make colloidal organic template particles having an average particle size in the range of 10 to 300 nm; which size can be controlled by the comonomer composition of the polyampholyte, and/or by selecting dispersion conditions.
The invention also relates to organic-inorganic or hollow-inorganic core-shell nano-particles obtained with this method, to compositions comprising such nano-particles, to different uses of said nano-particles and compositions, and to products comprising or made from said nano-particles and compositions, including anti-reflective coatings and composite materials.
