NOVELTY - Polymeric material comprises a polymerized reaction product of a polymerizable composition comprising components, where components comprises a uretdione-containing material comprising a reaction product of a diisocyanate reacted with itself; a first hydroxyl-containing compound having more than one OH group; and an optional second hydroxyl-containing compound having a single OH group, where the second hydroxyl-containing compound is a primary alcohol or a secondary alcohol; and 40 wt.% or greater of an inorganic filler, based on the total weight of the polymeric material; where the polymerized reaction product comprises a uretdione functionality of 1.3 to 2.5 and where the polymerized reaction product has a number average molecular weight (Mn) of 950 grams per mole (g/mol) or greater. USE - Polymeric material for two-portion composition (claimed). DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a two-portion composition, which comprises a first portion comprising a polymeric material comprising a polymerized reaction product of a polymerizable composition comprising components, the components comprising a uretdione -containing material comprising a reaction product of a diisocyanate reacted with itself; a first hydroxyl-containing compound having more than one OH group; and an optional second hydroxyl-containing compound having a single OH group, where the second hydroxyl-containing compound is a primary alcohol or a secondary alcohol; and 40 wt.% or greater of an inorganic filler, based on the total weight of the polymeric material; where the polymerized reaction product comprises a uretdione functionality of 1.3 to 2.5 and where the polymerized reaction product has a number average molecular weight (Mn) of 950 grams per mole (g/mol) or greater; and a second portion comprising at least one amine, at least one molecule of the at least one amine having an average amine functionality of 2.0 or greater, where each amine is a primary amine or a secondary amine; and 40 wt.% or greater of an inorganic filler, based on the total weight of the second portion; (2) a polymerized product of the two-portion composition; (3) a battery module, which comprises multiple battery cells connected to a base plate by a layer of the polymerized product; and (4) a method of adhering two substrates together, which involves obtaining a two-portion composition, combining at least a portion of the first portion with at least a portion of the second portion to form a mixture; providing at least a portion of the mixture on a first major surface of a first substrate; and contacting a first major surface of a second substrate with the mixture provided on the first substrate.
