    摘要： Chloral is copolymerized with one or more isocyanate, isothiocyanate, diisocyanate, diisothiocyanate or ketene compounds to produce copolymers which are nonflammable and which can be made into a variety of useful, shaped objects. The process of making the copolymers involves preparing a homogeneous mixture of monomers and polymerization initiator at a temperature above the threshold polymerization temperature of the mixture, cooling the homogeneous mixture below the threshold polymerization temperature and maintaining the homogeneous mixture quiescent during the polymerization.

    摘要： AN ADDITION COPOLYMER OF CHORAL AND AT LEAST ONE COMONOMER OF THE FORMULA R3-N=C=X WHEREIN X IS OXYGEN OR SULFUR AND R3 IS A NON-SUBSTITUTED HYDROCARBYL RADICAL. CHLORAL IS COPOLYMERIZED WITH ONE OR MORE ISOCYANATE, ISOTHIOCYANATE, DIISOCYANATE, DIISOTHIOCYANATE OR KETENE COMPOUNDS TO PRODUCE COPOLYMERS WHICH ARE NONFLAMMABLE AND WHICH CAN BE MADE INTO A VARIETY OF USEFUL, SHAPED OBJECTS. THE PROCESS OF MAKING THE COPOLYMERS INVOLVES PREPARING A HOMOGENEOUS MIXTURE OF MONOMERS AND POLYMERIZATION INITIATOR AT A TEMPERATURE ABOVE THE THRESHOLD POLYMERIZATION TEMPERATURE OF THE MIXTURE COOLING THE HOMOGENEOUS MIXTURE BELOW THE THRESHOLD POLYMERIZATION TEMPERATURE AND MAINTAINING THE HOMOGENEOUS MIXTURE QUIESCENT DURING THE POLYMERIZATION.

    摘要： The present invention is concerned with a method for improving the water storage capacity of textile substrates, particularly fleece based artificial leathers by treatment with a hydrophilizing agent. This agent, once applied to the substrate is insoluble in but swellable in water. The agent in an uncross-linked state is water soluble and has a turbidity point of between about 25.degree. and 95.degree. C. in a 25% aqueous solution. The agent may be applied to the substrate from aqueous solution and then cross-linked or it may be applied to an inert carrier such as kaolin, cross-linked and applied to the substrate from an aqueous suspension. A particularly suitable agent is a polyether with a molecular weight of between 500 and 8500, an ethylene oxide content of about 35 to 80 wt. % and cross-linkable end groups. The end groups may be self cross-linking such as vinyl groups or they may be cross-linkable via a cross-linking promoter such as hexamethylol melamine. These end groups include the hydroxyl groups normally present in polyethers produced from polyalkylene oxides.
