US7740938 2004年6月22日 2010年6月22日 Rhodia Polyamide Intermediates Dispersing a monomer solution in a liquid that is immiscible with the first solvent; and polymerizing by heating below the melting point of the formed polymer; mean particle size of less than 1 mm, especially less than 100 ...
The invention concerns polymerisable monomer compositions, transparent polymer substrates, and resulting optical and ophthalmologic articles, comprising 30 to 100 % of monomers of formula: (I) in which: R1, R2, R' and R' represent, independently of one another, a hydrogen atom or a methyl ...
The temperature and pressure conditions must be exact to produce the desired results, and the macroglycol and diisocyanate monomer must also be in a ratio approximate to 1:2. If the right conditions are applied, a substance called a prepolymer is formed, and this substance is then used in ...
A curable thermosetting polymer is formed from a monomer or a modified polymer containing maleimide, nadimide, or itaconimide; long shelf life at room temperature, low drying and curing temperatures; screen printing on copper substrate, connector with electroconductivity, nonabrasive, chemical ...
Monomer profiling of cell wall-associated and polymer-linked aliphatic suberin monomers in 1-month-old tomato roots revealed a predominance of α,ω-dicarboxylic acids, similar to potato12. Compared with Arabidopsis roots, which mostly feature ω-OH acids and a maximum chain length of 24 carbons...
1. Polymerisat herstellbar nach einem Verfahren umfassend a) Umsetzung von mindestens einem Polyisocyanat mit mindestens einem Polyol und mindestens einem radikalisch härtbaren Monomer A mit gegenüber Isocyanat reaktiven Gruppen in mindestens einem radikalisch härtbaren Monomer B zu Polyuretha...
For example, glycogenesis is the process of producing the carbohydrate polymer glycogen from glucose monomers, which in animals largely takes place within the liver in response to insulin. Firstly, glucose undergoes phosphorylation by glucokinase or other enzymes, depending on cell type and location, ...
ANXA2 exists as three major species: a monomer, a heterodimer, or a heterotetramer (AIIt) (3). The heterodimer is composed of a single subunit of ANXA2 bound to a subunit of 3-phosphoglycerate kinase (6). The heterotetramer, on the other hand, comprises two subunits of ANXA2 linked to...
Use of aqueous dispersions of (co)polymers (I) of at least one ethylenic unsaturated monomer for preparing textile additives, where (I) is prepared in the presence of at least two water-soluble polymer in which at least one water-soluble polymer is: graft polymer of vinyl acetate and/or ...
