The present invention provides a polymer which has a polymerizable functional group but still can be thermoformed without being crosslinked and which undergoes crosslinking upon irradiation with an active energy ray after being formed, and a composition including the polymer. An active energy ray crosslinkable thermoplastic polymer includes specific monomer units (1). The ratio of the number of moles of the monomer units represented by the general formula (1) to the number of moles of all monomer units constituting the polymer is not less than 1 mol %. The number average molecular weight (Mn) of the active energy ray crosslinkable thermoplastic polymer is 20,000 to 500,000.

A block copolymer and a use thereof are disclosed herein. The block copolymer of the present application may have excellent self-assembly properties or phase separation characteristics and simultaneously have characteristics capable of changing the self-assembly structure formed once, or provide a block copolymer capable of forming a pattern of phase separation structures in a polymer membrane.

The present disclosure relates a multilayered film that may include a first PET substrate, and a first anti-microbial coating overlying the first PET substrate. The first anti-microbial coating may include an acrylate-based component, and a silver-based filler component within the acrylate-based component. The first anti-microbial coating may have a MRSA anti-microbial rating of at least about 75%, where the MRSA anti-microbial rating is defined as the percent reduction of methicillin-resistant Staphylococcus aureus (MRSA) activity from an initial inoculation of MRSA on the surface of the anti-microbial layer after 24 hours as measured using ISO22196.

A modified conjugated diene-based polymer and a rubber composition including the same are disclosed herein. The modified conjugated diene-based polymer has excellent processability and good tensile strength and viscoelasticity. In some embodiments, a modified conjugated diene-based polymer includes a derived unit from a modifier, the modifier including three or more alkoxy groups bonded to silicon; a non-functional chain forming a silicon-carbon bond at one side of the derived unit from a modifier and including a repeating unit derived from a conjugated diene-based monomer; and a functional chain forming a silicon-carbon bond at the other side of the derived unit from a modifier and including two or more derived units from an N-functional group-containing monomer.

Described herein are depolymerized polystyrene resins derived from polystyrene source resins. The depolymerized polystyrene resins undergo a depolymerization in which chemical bonds are cleaved, producing depolymerized polystyrene resins of lower molecular weight. The polystyrene resins may be modified by chemical reaction with monomers, polymers, and oligomers, such as acrylates thereof. Also described are ink and coating compositions that include the depolymerized and modified polystyrene resins.

Provided is a hydrogel-forming composition capable of forming a sterilized hydrogel having a high mechanical strength. Also provided are a hydrogel using the hydrogel-forming composition, and a method for producing the hydrogel-forming composition. The hydrogel-forming composition contains a vinyl alcohol polymer having an ethylenically unsaturated group and having a polymerization degree of 450 or more, in which the ethylenically unsaturated group introduction ratio is 0.01 to 10 mol % in all the structural units constituting the vinyl alcohol polymer, and in which no microorganisms detectable by the sterility test method (direct method) specified in the general test methods of the Japanese Pharmacopoeia are present.

Polydiallylamine copolymers are copolymers comprising monomers of polydiallylamine and either polyvinlyamine or polyallylamine. Polydiallylamine copolymers are often crosslinked. The polydiallyamine copolymers are useful as pharmaceutical compositions and may be used in the treatment of type 2 diabetes and for mitigating the complications of type 2 diabetes.
