Block-modified polysiloxanes and compositions comprising the block-modified polysiloxanes are useful in the field of textile finishing. Emulsions comprising the compositions have a very small and narrowly distributed particle size which increases penetration, and provide good softening properties coupled with good hydrophilicity.

The invention relates to a process for preparing a polyurea or a polyurethane organopolysiloxane block copolymer having a silicone content of at least 90% in weight relative to the total weight of the organosiloxane block copolymer. The invention further relates to a polyurea or a polyurethane organopolysiloxane block copolymer obtained according to this process and its use in a method for manufacturing a 3D article by an additive technique.

Described herein is a method for producing HEVL-filtering contact lenses in a relatively efficient and consistent manner from a polymerizable composition under a controlled thermal curing scheme. The polymerizable composition comprises at least one N-vinyl amide monomer and at least one Cu(II)-meso-aryl-substituted porphyrin free of any ethylenically unsaturated group. The resultant HEVL-filtering contact lenses each comprise a polymer matrix to which the Cu(II)-meso-aryl-substituted porphyrin is grafted or covalently attached.

An aqueous of pre-crosslinked organopolysiloxanes and process for producing the same. The aqueous dispersion is preferably aqueous emulsion, including pre-crosslinked organopolysiloxanes which contains on average at least one structural unit of the general formula SiRO.sub.2/2—Y—SiRO.sub.2/2 and units of the formula R.sub.2SiO.sub.2/2. Where Y is a radical of the formula

—R.sup.2—[NR.sup.3—R.sup.4—].sub.x—NR.sup.3—OC—[C(Z.sup.1)(H)].sub.k1—[C(Z.sup.2)(H)].sub.k2—CO—NR.sup.3—[R.sup.4—NR].sub.x—R.sup.2

and where R, R.sup.2, R.sup.3, R.sup.4, k1, k2, x, Z.sup.1 and Z.sup.2 have a definition a set forth within herein. Additionally, the sum of k1+k2 is ≥1, the that at least one radical Z.sup.1 or Z.sup.2 is a hydroxyl or NHR.sup.3 group, preferably a hydroxyl group, and so the bridging group Y contains at least one hydroxyl or NHR.sup.3 group, preferably at least one hydroxyl group.

Functionalized silicone polymers incorporating segments formed from medium-chain fatty acids are generally disclosed herein. Methods of using such compounds, for example, as surfactants, are also disclosed herein, as well as methods of making such compounds, for example, from medium-chain fatty acids derived from natural oils.
