The present invention relates to a selective process for producing polyurethane prepolymers, to the polyurethane prepolymers obtainable from this process, and also to a process for producing moisture-crosslinking silylated polymers, more particularly silane-functional hybrid polymers, and also to the use thereof in CASE sectors (coatings, adhesives, sealants and elastomers).

The invention relates to a composition and to a process for preparing moisture-crosslinking polymers under catalysis by at least one metal-siloxane-silanol(ate) compound, and to the use of the composition in the CASE sector (coatings, adhesives, sealants and elastomers), especially in the field of adhesives and sealants.

An image forming apparatus at least includes: an image bearing member; a developer container; a developer carrying member; and a controller that controls a power source that applies a voltage to the developer carrying member, wherein the developer carrying member has at least a base and a surface layer, the surface layer has an electron donating portion that mainly donates charge to the developer when the developer and the surface layer makes frictional contact to exchange charge and an electron accepting portion that mainly accepts charge from the developer, and the controller applies an AC voltage to the developer carrying member during a period in which an image forming operation is not performed and the developer carrying member is driven, the AC voltage being different from that applied during an image forming period.

The present invention relates to a selective process for the preparation of NCO-functionalized polyols, to their use in the preparation of silylated polyurethanes, to processes for preparing silylated polyurethanes and to silylated polyurethanes obtainable by a reaction of NCO-functionalized polyol with amino silane and to their use in CASE applications (coatings, adhesives, sealants and elastomers).

The invention relates to a composition comprising and to a process for preparing moisture-crosslinking polymers under catalysis by a metal-siloxane-silanol(ate) compound, and to the use of the composition in the CASE sector (coatings, adhesives, sealants and elastomers), especially in the field of adhesives and sealants.

Embodiments of the present disclosure are directed towards solventless compositions that include a reaction product formed by reacting a polyol and an aminopolycarboxylic compound.

The invention relates to the use of at least one metal-siloxane-silanol(ate) compound for selective catalysis of the gel reaction in a system for the production of polyurethanes, preferably of unfoamed polyurethanes, flexible foams or rigid foams and/or in the two-component (2K) system according to the invention, and to processes for producing foamed or unfoamed polyurethanes, especially flexible foams or rigid foams, and to use in the CASE sector (coatings, adhesives, sealants and elastomers), furniture, mattresses, car seats, seal materials or acoustic materials, for insulation of district heating pipes, tanks and pipelines, and for production of all kinds of refrigeration units. In a further aspect, the invention relates to unfoamed polyurethanes, flexible foams and/or rigid foams each produced through the inventive use of at least one metal-siloxane-silanol(ate) compound for selective catalysis of the gel reaction.

Embodiments of the present disclosure are directed towards solventless compositions that include a reaction product formed by reacting a polyol and an aminopolycarboxylic compound.

An image forming apparatus includes a developer carrying member that bears and conveys developer. The developer carrying member has at least a base and a surface layer, with the surface layer having an electron donating portion that mainly donates charge to the developer when the developer and the surface layer make frictional contact to exchange charge and an electron accepting portion that mainly accepts charge from the developer when the developer and the surface layer makes frictional contact to exchange charge. A controller applies an AC voltage to the developer carrying member during a period in which an image forming operation is not performed and the developer carrying member is driven, with the AC voltage being different from that applied during an image forming period, and a rotating speed of the developer carrying member during a non-image forming period is slower than that during an image forming period.

The present invention relates to a selective process for producing polyurethane prepolymers, to the polyurethane prepolymers obtainable from this process, and also to a process for producing moisture-crosslinking silylated polymers, more particularly silane-functional hybrid polymers, and also to the use thereof in CASE sectors (coatings, adhesives, sealants and elastomers).
