Pre-polymers - structure

Prepolymers are compounds that enable modifying of isocyanates with high molecular weight alcohols or other compounds with carboxyl or amine groups, to obtain the desired properties in the target system. The isocyanate prepolymers contain reactive NCO groups that react with hydroxyl or amine groups, resulting in chain extension and the formation of a finished material. They are characterized by the ability to regulate the content of free isocyanate groups (-NCO) as needed. Representatives of this group of compounds are prepolymers based on aromatic isocyanates (MDI, TDI) or aliphatic (IPDI, HDI, H12MDI etc.).

SALTS - structure and production

Salts are chemical compounds formed as a result of a reaction between an acid and a base.

SILICON - structure and production

Silicon is a chemical element that belongs to the half-metal group. It is found primarily in the outer layers of the Earth.

SORBITAN ESTERS - structure and obtaining

Sorbitan esters belong to non-ionic surfactants. The raw material for their production is sorbitol, a six-hydroxy sugar alcohol, obtained by reducing glucose. This reaction changes the aldehyde group to hydroxyl group. Sorbitol during dehydration loses one molecule of water, forming sorbitan, i.e. a mixture of cyclic ethers. It consists of 15% tetrahydropyran and 85% tetrahydrofuran. Further dehydration results in the formation of a bicyclic derivative called sorbide.

Structure and preparation of polyalkylene glycol (PAG)

Polyalkylene glycols (PAGs) are polymers obtained by reaction of alkyl oxides, such as ethylene, propylene or butylene oxide, with compounds containing active hydrogen. Most often they are mono- or polyhydric alcohols and organic acids. The most popular polyalkylene glycols are homopolymers of ethylene and propylene oxide as well as block and statistical copolymers EO / PO.

Structure of amino acid surfactants

Amino acid surfactants belong to the group of anionic surfactants. Their molecules are made of polar amino acids (hydrophilic moieties) and long-chain compounds that are hydrophobic. They are made on the basis of biomimetics – raw materials that mimic the chemical compounds of natural origin. The fatty acids derived from vegetable raw materials are also used for the production of amino acid surfactants.
