This invention relates to a process for forming an azide-grafted polymer. The process comprises mixing a free-radical-reactive polymer with a free-radical initiator and an azide monomer that contains at least one unsaturated C═C bond capable of reacting with a radical, under solid-state grafting conditions, to form an azide-grafted polymer. The formed azide-grafted polymer can be used to prepare a long-chain branched or cross-linked polymer.

Disclosed herein are novel graft polymers including a block copolymer backbone (A) as a graft base having polymeric sidechains (B) grafted thereon. The polymeric sidechains (B) are obtainable by polymerization of a vinyl ester monomer (B1) and optionally N-vinylpyrrolidone as optional further monomer (B2). Most preferably, the block copolymer backbone (A) is a triblock copolymer of polyethylene oxide (PEG) and polypropylene oxide (PPG). Further disclosed herein is a process for obtaining such a graft polymer Further disclosed herein is a method of using such a graft polymer within, for example, fabric and home care products. Additionally disclosed herein are fabric and home care products containing such a graft polymer.

Provided is a polymer functioning as a leveling agent that imparts high smoothness to a coating film. Specifically, a polymer containing a polymer block (A1) of a polymerizable monomer (a1) having a functional group represented by —Si[OSi(R).sub.3].sub.n[R′].sub.3-n (n is an integer of 1 to 3, each R independently represents an alkyl group having 1 to 3 carbon atoms, and each R′ independently represents an alkyl group having 1 to 3 carbon atoms). Also provided are a coating composition, a resist composition, and an article containing the polymer.

The invention relates to on-demand debondable pressure sensitive adhesive and laminating adhesive compositions and uses thereof. The debondable pressure sensitive adhesives and laminating adhesives are applied onto a substrate to form a bond, and upon exposure to electron beam or UV light energy source, the adhesive can dissociate from the substrate. The debondable pressure sensitive adhesives and laminating adhesives are particularly suitable for recycling in a circular economy.
