SummariesThe chemistry of polyurethanes, polyureas, polyurethane dispersions and their reaction partners such as oxazolidines continues to grow judging by the number of patent applications and papers published. The application areas of these products also continues to increase. This paper presents a review of past and current technology including examples of the synthesis of the above species. Hybridisation of these systems is in vogue and this trend will continue. Some chemical synthesis… 
Linear polyurethanes derived from alditols and diisocyanates
A set of linear [m,n]-type polyurethanes was synthesized by polycondensation in solution from hexamethylene diisocyanate and 4,4′-methylene-bis(phenyl isocyanate) with alditols. Threitol, arabinitol,
Linear polyurethanes made from threitol: Acetalized and hydroxylated polymers
A set of novel linear polyurethanes was synthesized by reaction in solution of 1,6-hexamethylene diisocyanate (HDI) or 4,4′-methylene-bis(phenyl diisocyanate) with 2,3-acetalized threitols,
A Review on Waterborne Thermosetting Polyurethane Coatings Based on Castor Oil: Synthesis, Characterization, and Application
ABSTRACT Waterborne polyurethane coatings made from castor oil as polyol resource, replacing oil from fossil fuels are attracting lot of recognition during recent decades. In this review, castor oil

Oxazolidines and tetramethylxylenediisocyanate based polyurethanes in legislation-compliant anticorrosion coatings
ConclusionThe use of polyurethanes continues to expand and newer technology has fuelled this growth. The development and commercial introduction of new isocyanates such as TMXDI™ has also spurred on
The synergy between water-borne epoxy and high solids polyurethane legislation compliant coatings
SummaryThe coatings industry is under pressure to reduce the Volatile Organic Content (VOC) of coating systems. One way of doing this, is to design the resin and coating with water as the liquid
Water-borne polyurethane dispersions and their use in functional coatings
ConclusionsThere were high hopes and many predictions in the 1970s that the coatings industry would rapidly move to water-borne coatings. This did not occur in this very traditional and conservative
Legislation‐compliant polyurethane and epoxy coatings
Legislation is currently the key driver in the coatings industry. Reduction of the volatile organic content (VOC) of coating systems is a main aim. This may be achieved by designing the resin and
