Polyurethane-modified addition copolymers preparable by free-radically (co)polymerizing an olefinically unsaturated monomer (a) in an aqueous or nonaqueous medium comprising at least one reaction product (A/B) of (A) at least one addition copolymer containing on average per molecule at least 0.1 isocyanate-reactive functional groups and preparable by free-radical copolymerization of at least 

Polyurethane-modified copolymers, method for their production and the use thereof

Novel polyurethanes containing sulfide groups which comprise at least one group of the general formula I in the polymer main chain and/or at least one group of the general formula II incorporated at the chain end:&#x2014;X&#x2014;A&#x2014;S&#x2014;B&#x2014;Y&#x2014;&#x2003;&#x2003;(I)&#x2014;X&#x2014;A&#x2014;S&#x2014;B&#x2014;YH&#x2003;&#x2003;(II)in which the variables have the following definitions:

Polyurethanes containing sulphide groups, polymeric mixtures based thereon, production and use thereof

A hydrophilic or hydrophobic polyurethane containing on average per molecule at least one olefinically unsaturated structural unit selected from the group consisting of pendant, internal, and terminal, acyclic and cyclic terpene units; graft copolymers of the polyurethane with olefinically unsaturated monomers, processes for preparing the polyurethane and the graft copolymers, and their use for preparing coating materials, adhesives, and sealing compounds.

Polyurethane and polyurethane-based mixed graft polymers and their use for producing coating materials, adhesives and sealing compounds

The invention relates to a method of producing color pastes, in which a component comprising colorant particles is dispersed in a binder. In the method of the invention the dispersing operation is controlled by beaming excitational light of a defined wavelength range into a mixture of the component comprising colorant particles and the binder, detecting the light transmitted, reflected and/or scattered by the mixture and determining a sample spectrum, evaluating the sample spectrum and hence determining parameters of the color paste, and monitoring changes in the sample spectrum over time and terminating the dispersing operation when predetermined target parameters are attained.
