A binder composition for a non-aqueous secondary battery contains: a particulate polymer formed of a graft polymer that includes an acidic graft chain and that is obtained through a graft polymerization reaction of an acidic group-containing monomer and/or macromonomer with core particles containing a block copolymer that includes an aromatic vinyl block region formed of an aromatic vinyl monomer unit and an aliphatic conjugated diene block region formed of an aliphatic conjugated diene monomer unit; and an acidic group-containing water-soluble polymer that has a weight-average molecular weight of 200,000 or less.

A statistical, cationic-functionalized norbornene copolymer is formed by a process including performing a vinyl addition polymerization in the presence of a metal catalyst of a first norbornene monomer substituted with a first alkyl group and at least a second norbornene monomer substituted with a second alkyl group, to form an intermediate norbornene copolymer. The second alkyl group includes a substituent which undergoes a substitution reaction with a precursor of a cationic group. The process further includes adding the precursor for the cationic group to the intermediate norbornene copolymer to form the cationic functionalized norbornene copolymer. The cationic group has a volume of 0.25 cm.sup.3/mol or greater (for example, a phosphonium group or an imidazolium group).

According to various embodiments of the present disclosure, a composition includes about 5 to about 40 parts by weight of a solute copolymer component. The solute component optionally has one T.sub.g or T.sub.m of at least 25° C. The composition further includes about 60 to about 95 parts by weight of a solvent monomer. The solvent monomer component includes (meth)acrylate monomers and a multifunctional acrylate. The sum of the solute copolymer component and the solvent monomer component is 100 parts by weight. The composition further includes about 5 to about 100 parts of a plasticizer, relative to the 100 parts.

A curable primer composition comprising:(a) a curable component such as methacrylate; (b) a cure initiating component; and (c) a polymer material selected from the group consisting of: (i) block polymers represented by S-A-S where S is polystyrene and A stands for a polymer or copolymer formed from one or more of ethylene, propylene, butylene, and styrene, which are optionally substituted with carboxylic acid or maleic anhydride; provided that when A comprises styrene then A is a copolymer of styrene with at least one of ethylene, propylene and butylene, and is optionally substituted with carboxylic acid or maleic anhydride; and (ii) polystyrene-poly(ethylene-propylene) (“SEP”); and (iii) any combination of said polymer materials. The composition is applied to a part then photocured. It is dry to touch. Thereafter a thermoplastic material such as a polyolefin is overmolded (e.g. injection molded) over the applied composition. It enhances bond strength of the polyolefin to the part.
