An example of a bottlebrush polymer has a polymer backbone and a plurality of individual brush moieties bonded to the polymer backbone. The individual brush moieties respectively including a ketone, a hydrophilic segment, and a surface adhesive terminal group. The brush moieties can be functionalized and/or cross-linked.

A circular tire frame includes a resinous material including a polyamide-based thermoplastic elastomer. The polyamide-based thermoplastic elastomer is a copolymer formed by polymerization of at least a polymer (HS) forming a hard segment and a polymer (3SS) forming a soft segment and having three or more functional groups.

A process for preparing a low-molecular weight fluoropolyether containing an acid fluoride by decomposing a triflate or trifluoroacetate of a fluoropolyether having a hydroxyl group in the presence of a Lewis acid.

The invention provides for dry spray compositions comprising co-polymers comprising a core, water-soluble polymer and a peptide.

The present invention provides nanomaterials for the specific targeting of immune cells. Methods of treating cardiac disease and inflammatory disease are also described.

A method of production of a polyether rubber containing units expressed by the following general formula (1) in 0.1 mol % to less than 30 mol % including reacting a polyether rubber containing epihalohydrin monomer units in 0.1 mol % or more and a nitrogen atom-containing aromatic heterocyclic compound by kneading in the presence of an acid acceptor using an extruder-kneader so as to make at least part of halogen atoms forming the epihalohydrin monomer units be substituted by a group containing a cationic nitrogen-containing aromatic heterocyclic structure is provided. ##STR00001## (wherein, in the above general formula (1), A.sup.+ is a group containing a cationic nitrogen-containing aromatic heterocyclic structure, where the group containing a cationic nitrogen-containing aromatic heterocyclic structure is bonded with a carbon atom at the 2 position shown in the above general formula (1) through a nitrogen atom forming the cationic nitrogen-containing aromatic heterocyclic structure, and X.sup. is any counter anion.)

A non crosslinked, covalently crosslinked and/or ionically crosslinked polymer, having repeating units of the general formula (1)

KR(1)

In which K is a bond, oxygen, sulfur,

##STR00001##

the radical R is a divalent radical of an aromatic or heteroaromatic compound.

A polymer of fluorine-containing sulfonated poly(arylene ether)s and a manufacturing method thereof are provided. The polymer is formed by processing a nucleophilic polycondensation between a fluorine-containing monomer having an electron-withdrawing group and a multi-phenyl monomer. A main structure of the polymer of fluorine-containing sulfonated poly(arylene ether)s has a first portion with fluoro or trifluoromethyl substituted phenyl groups, and a second portion with sulfonated phenyl groups.

The invention relates to (among other things) oligomer-foscarnet conjugates and related compounds. A conjugate of the invention, when administered by any of a number of administration routes, exhibits advantages over previously administered un-conjugated foscarnet compounds.

A circular tire frame includes a resinous material including a polyamide-based thermoplastic elastomer. The polyamide-based thermoplastic elastomer is a copolymer formed by polymerization of at least a polymer (HS) forming a hard segment and a polymer (3SS) forming a soft segment and having three or more functional groups.
