The present invention relates to radiation of dual radiation/moisture curable compositions based on (meth)acrylate- and silane-terminated polymers that can be used as 3D printing materials and provide isotropic and elastomeric properties. The invention further relates to the use thereof as 3D printing materials and printing methods using said compositions.

Radiation curable and printable composition

The invention relates to a bi-functionalized polysiloxane brush copolymer comprising at least one hydroxyl-terminated polyalkyleneglycol side chain and at least one onium-functionalized side chain as defined herein, and a method for preparing the bi-functionalized polysiloxane brush copolymer, a curable composition comprising the bi-functionalized polysiloxane brush copolymer and its use.

Bi-functionalized polysiloxane brush copolymers

The present disclosure relates to a radiation or radiation/moisture dual curable compositions based on (meth)acrylate polymers or (meth)acrylate- and silane-terminated polymers. The invention further relates to their use as an adhesive, sealant and/or coating material, and adhesive, sealant and/or coating materials comprising said curable composition thereof.

Radiation curable composition with improved mechanical properties

The present invention relates to an onium-functionalized siloxane having the general Formula (X) or (X-A) as defined herein; a method for preparing the onium-functionalized siloxane; and its use as an antimicrobial agent.

Onium-functionalized siloxanes

The invention relates to a curable composition comprising: a) at least one polymer having at least one silicon-containing group of formula —Si(R)(Y)as defined herein, and b) at least one hydroxyl-functionalized polysiloxane polyalkyleneglycol brush copolymer of the structure [A(-X—B)]as defined herein; and an adhesive, sealant, or coating material comprising said curable composition and use thereof.

Curable composition comprising polysiloxane polyalkyleneglycol brush copolymers

The present invention relates to a procedure in which a functionalized polysiloxane is synthesized in the presence of a platinum catalyst, and halogen-functionalized polysiloxanes obtained according to the procedure. The procedure is defined herein by reacting a) at least one polysiloxane comprising at least one hydrogen atom bonded to a silicon atom; b) at least one heterocyclic compound; and c) at least one halogen-containing compound, wherein the reaction is catalyzed by at least one platinum catalyst. The synthetic pathway is described as a halosilation reaction in which a heterocyclic molecule is ring-opened in the presence of a platinum catalyst and a halogen source, resulting in a formal insertion of the opened heterocycle into the SiH bond. On the final product, the heteroatom of the former heterocycle is bonded to the silicon atom from the former hydrosiloxane moiety while the halogen is bonded to the last carbon atom of the opened chain.

Method for preparing halogen-functionalized polysiloxanes

The present invention relates a hydroxyl-functionalized unimodal polysiloxane polyalkyleneglycol brush copolymer of the structure [A(-X—B)], wherein: A represents said polysiloxane backbone; B represents said polyalkyleneglycol side chain; X is a linker group characterized by including the moiety Si—C—C— of which said Si is a part of the polysiloxane backbone A; and s is an integer of from 1 to 100, wherein the polysiloxane backbone A contains less than 500 ppm mol % of SiH moiety based on the total moles of the silicon atom which constitutes the polysiloxane backbone, and said copolymer has a polydispersity index of from 1.3 to 5.0; and a method for producing said hydroxyl-functionalized unimodal polysiloxane polyalkyleneglycol brush copolymer.
