A method for forming a polydisulfide polymer is described. In various implementations, the method includes forming a mixture including one or more thiols, agitating the mixture, precipitating the mixture, and extracting a polydisulfide polymer from the mixture. In various implementations, the polydisulfide polymer has a refractive index of at least 1.7.

Inhibition by oxygen of the peroxide-initiated cure of a composition based on (meth)acrylates or other compounds containing free radical-polymerizable functional groups is mitigated by inclusion of one or more polythiols in the composition. Such compositions may be formulated as multi-part systems, which are useful for the preparation of coatings and sealants.

The present invention relates to a curable composition which can be cured by radiation and/or the influence of temperature; a cured product which is obtained from such a composition; an object and a composite which have the cured composition; and a method for producing the same. The cured composition has a high refractive index.

The invention pertains to a polyarylether sulfone polymer [polymer (PAES)] incorporating recurring units derived from well-defined amount of bi- or poly-functional monomers having identical functionalities in each of their reactive groups in a chain of units derived from of a monohalo-monohydroxyl arylsulfone monomer comprising groups of formula (A), free from hydroxyl groups which are bound to a phenyl ring comprising an activating SO.sub.2 group in para-position, while comprising an activated aromatic halogen bound to a phenyl ring comprising an activating SO.sub.2 group in para-position, having improved balance between mechanical properties and viscosity in the molten state, and endowed by lower polydispersity indexes with respect to materials of the prior art, to a method for making the same, to polymer compositions comprising the same, and to shaped articles therefrom.

Disclosed herein are poly(hydroxylalkyleneimine disulfide)polymers, which have both desirable transfection properties and reduced toxicity.
