摘要： The invention relates to a process for producing a ring-opening polymerization product by reacting at least one polyisocyanate and 2-oxo-1,3-dioxolane-4-carboxylic acid and subjecting the reaction product to a temperature within the range of from about 40 to about 150° C. in the presence of a catalytic amount of at least one non-nucleophilic base. The obtained polymerization product may be present as a foam and is suitable as binder, insulation material, sealant or coating and in the production of mattresses or wound pads.

摘要： An elongated pipe may include a fiber reinforced polymer composite joining member for joining sections of pipe together. A pipe joint and elongated pipe may include at least two pipe sections having ends that are joined together with the joining member. The pipe joint and elongated pipe are formed by joining abutting ends of adjacent pipe sections with the joining member without the need for the adjacent pipe sections to have other connection means, such as standard bell and spigot end connections. A method may include joining pipe sections with the joining member to make an elongated pipe.

摘要： The present invention relates to cationic copolymers, a process for the production of these cationic copolymers and the use of these cationic copolymers as dispersants for geopolymer binder systems. These cationic copolymers where the cationic charge is due to the presence of certain cyclic and/or polycationic groups are stable towards Hoffmann elimination that would otherwise occur at very high pH values. Moreover, the dispersing effect of cationic polymers can be further enhanced through the addition of polyvalent anions.
