The present invention relates to a resin composition that comprises an acetoacetate ester compound with at least two acetoacetate ester functional groups, an acrylate compound with at least two acrylate functional groups, and a tertiary amine curing catalyst. This resin composition acts as an isocyanate-free binder that is less toxic to the environment. The invention further discloses a method for preparation fiber reinforced parts comprising fibers and said resin composition as well as a method for the preparation of foundry molds for the casting industry, which is based on said binder.

The invention provides powerful methods and compositions for designing, selecting, fine-tuning and optimizing polymer nanogel and other supramolecular assemblies for various properties including, for example, particle size, density and morphology, guest loading capacity and encapsulation stability, and dynamic release control.

Described herein are water-soluble UV-absorbing vinylic monomers and their uses in preparing UV-absorbing contact lenses capable of blocking ultra-violet (“UV”) radiation and optionally (but preferably) violet radiation with wavelengths from 380 nm to 440 nm, thereby protecting eyes to some extent from damages caused by UV radiation and potentially from violet radiation. This invention also provides a UV-absorbing contact lens.

A material non-adhesive to a biological substance containing: a polymer compound (A) which includes a repeating unit derived from a sulfobetaine monomer represented by Formula (I) or (II).
