Described is a silicone hydrogel contact lens having non-uniform morphology. The contact lens may be made from a reactive mixture comprising: a silicone-containing component; a hydrophilic component; a non-reactive polymeric internal wetting agent; and a polymerization initiator, the contact lens having an oxygen permeability of at least about 60 barrers, and wherein the molar ratio in the lens of the polymeric non-reactive internal wetting agent to silicone, without a surface treatment, is greater in the lens's surface than in its bulk.

Moisture curable polyacrylate polymers with pedant moisture reactive silyl-functional groups bound to the polymer chain and compositions comprising the same polyacrylate polymers are provided. The polyacrylate polymers and the compositions cure by way of a condensation mechanism in the presence of moisture and a catalyst. The moisture curable polyacrylate polymers and compositions provide excellent resistance to automotive oil at high temperature and are particularly useful as sealants and gaskets in automotive powertrains.

A hydrophilic siloxane copolymer of siloxane and hydrophilic organic monomer/s The copolymers can be functionalized to make them capable of undergoing further polymerization by thermal or actinic radiations. The hydrophilicity of these polymers can be varied by varying the siloxane versus organic monomer ratio thereby going from water dispersible to soluble states. The siloxane content can be tuned accordingly in order to provide moderate to high oxygen permeability. These copolymers can be used as a single component curable composition which results in hydrogels to minimize the presence of leachable components thus by reducing the processing cost. The polymers may also find applications in personal care formulations as copolymers, film-formers, hydrogels, coating, emulsions/latex etc.

A roofing membrane and a method of making the same is provided. The roofing membrane includes a top layer having a flame retardant and a first silane-crosslinked polyolefin elastomer with a density less than 0.90 g/cm.sup.3; a scrim layer; and a bottom layer having a flame retardant and a second silane-crosslinked polyolefin elastomer with a density less than 0.90 g/cm.sup.3.
