A process prepares a prepolymer containing a urethane group and a curable silicon-functional group, or a prepolymer of formula (IV), ##STR00001##
The prepolymer may be cured to a cross-linked polymer by ambient moisture and is therefore suitable for use as a component in a one-component sealant or adhesive composition.

Provided are a solvent-free two-component type adhesive capable of guaranteeing a practical packaging property, with an excellent curing property and significantly shortening aging time, a laminated film using the same, and a polyol composition for an adhesive. An adhesive, characterized in comprising a polyisocyanate composition (X) containing a polyisocyanate (A), and a polyol composition (Y) containing a polyol (C) and a tertiary amine compound (B) having multiple hydroxyl groups, as necessary components.

Provided is an adhesive comprising a reaction product of (A1) an aliphatic isocyanate having an NCO group content of 18 to 64 and (A2) a polyol or polyamine having a molecular weight of from 400 to 4000; and (B) a polyaspartate compound, wherein viscosity of the adhesive, as measured @ 23° C. according to ASTM D4212-16, remains below 60 seconds for after four hours, and wherein the adhesive develops an acceptable bond strength to a substrate, defined as having a minimum of 150 g/in. measured @ 23° C. according to ASTM D 1876-01 or substrate tear, in less than or equal to five days after the substrate is laminated with the adhesive. The adhesives are free of aromatic amines and may find use in multi-layered laminated films for the production of flexible packaging useful in a variety of industries, including the food processing, cosmetics, and detergents industries.

An adhesive composition comprising a polyurethane and a cationic polymeric dopant or a polymerizable cationic dopant may be used to form one or more adhesive layers of electro-optic assemblies. They enable improved electro-optic performance of the corresponding electro-optic devices even at low temperatures.

A process prepares a cross-linked polymer containing urethane groups and silicon atoms. Starting materials of the process include a compound A) with a five-membered cyclic monothiocarbonate group, a compound B) with an amino group, selected from primary or secondary amino groups or blocked amino groups, and optionally, a compound C) with at least one functional group that reacts with a group —SH. One of the compounds contains a silicon-functional group. In one example of the process, compounds A) and B), and optionally C), are then reacted under exclusion of water to obtain a polymer with curable silicon-functional groups. The polymer is applied to a surface, gap, or a three-dimensional template. The silicon-functional groups are cured with ambient water. The polymer contains 0.001 to 0.3 mol of silicon per 100 g of the polymer.
