A curable composition that gives a cured product exhibiting a high refractive index and a surface without defects such as roughness or cracks, a cured product of the composition, and a compound that may be blended to the composition. A triazine compound is used as a curable component in a curable composition, the triazine compound having an optionally substituted quinolinyl group, an optionally substituted isoquinolinyl group, or an optionally substituted 2-substituted benzothiazolyl group and an aromatic-ring-containing group having a radically polymerizable group-containing group or an aromatic-ring-containing group having a cationically polymerizable group-containing group, each group bonded to the triazine ring via an amino group.

Disclosed herein is a polymerization process involving the steps of generating monomer micro-volumes in a microfluidic device, feeding the monomer micro-volumes through the at least one first microfluidic channel towards a monomer feed point at which the monomer micro-volumes enter into or onto a volume of a non-aqueous liquid and form aqueous monomer droplets, allowing the aqueous monomer droplets to flow towards a polymer bead discharge point, initiating polymerisation of the aqueous monomer droplets to form polymerising beads, removing a suspension of the polymer beads in the non-aqueous liquid from the vessel at the polymer bead discharge point, and recovering water soluble or water swellable polymer beads from the suspension. The present disclosure also includes an apparatus for performing the polymerization process and water soluble or water swellable polymer beads obtained by the polymerization process.

This invention relates to cyanoacrylate-containing compositions, which when cured provide improved heat resistance.

Improved emulsion breakers in the form of polyol acrylate polymers in water/oil emulsions have relatively high polymer contents and low inversion viscosities. The emulsion breakers can be prepared by mixing together acrylate monomer, polyol, water, liquid petroleum product, and emulsifier, followed by homogenization of the mixture; the latter is then subjected to free radical polymerization to polymerize the polyol and monomer in situ within the mixture.

This invention relates to cyanoacrylate-containing compositions, which when cured provide improved heat resistance.
