    摘要: In the preparation of polyarylene sulfide (PAS) by reacting an alkali metal sulfide with a dihaloaromatic compound in an organic amide solvent to obtain a polyarylene sulfide slurry and subjecting the slurry to acid treatment, an acid or hydrogen salt is added to the slurry in such an amount that a pH of the slurry is more than 7.0 and at most 11.0 to carry out the acid treatment. Alternatively, a zinc compound in an amount of 0.1 to 1.5 mole % per mole of the alkali metal sulfide supplied is added to the polyarylene sulfide slurry to treat the slurry, and, then, an acid or hydrogen salt in an amount of at least 0.2 mole % per mole of the alkali metal sulfide supplied is added. The PAS thus obtained has high crystallization speed, high whiteness, high mechanical strength and high melt viscosity, V6.

    摘要: The invention pertains to a coating composition comprising a first compound comprising at least one bicyclo- or spiro-orthoester group and a second compound comprising at least two hydroxyl-reactive groups. The invention also comprises a process for curing the present coating composition. More particularly, the latent hydroxyl groups of the bicyclo- or spiro-orthoester groups have to be deblocked and reacted with the hydroxyl-reactive groups of the second compound if the present coating composition is to be cured. Further, a process for making bicyclo-orthoester compounds from the corresponding oxetane compound is described, as are polymers comprising at least one bicyclo- or spiro-orthoester group.
