In one aspect, the invention relates to methods of synthesizing acryloyl compounds, comprising the step of hydrosilylating a compound having the structure: with a compound having the structure A-H, wherein A comprises a siloxanyl group, to yield a compound having the structure: Compounds and compositions produced thereby can effectively attain a satisfactory balance between high oxygen permeability and hydrophilicity while achieving an acceptably low concentration of undesirable impurities. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present invention.

Acryloyl materials for molded plastics

The resin of the invention comprises both a phosphorus-containing residue having a bicycloalkyl structure and a specific divalent phenol residue. The invention provides a resin having excellent optical properties, which is colorless and transparent, has a high refractive index and is optically low dispersive, as well as its molded product.
