    • Composition comprising a linear saturated polyester and from 0.5 to 30 percent by weight of the polyester of at least one ester of an ethoxylated polyfunctional alcohol having a molecular weight of from 500 to about 1,500. The ester is of an ethoxylated aromatic alcohol and a carboxylic acid wherein the ethoxylated aromatic alcohol has the formula, HO (RO)n - R - (OR)n - OH; wherein R is the same of different hydrocarbon radical of from 2 to 4 carbon atoms, n can be the same or a different integer of from 2 to 15; and R is an aromatic radical preferably derived from an aromatic dialcohol, most preferably bisphenol A. The ethoxylated aromatic alcohol has greater than 20 carbon atoms. The acid is a carboxylic acid of from 1 to 25 and preferably 3 to 10 carbon atoms, and from 1 to 10 carboxyl groups. Preferably the acid has from 3 to 10 carbon atoms and one carboxyl group.

    • Compositions and methods for priming or sealing dental or biological substrates for subsequent bonding. The primer is particularly useful for priming dentin of a tooth to prepare the dentin for bonding with a resinous material. The primer comprises a mixture of a polymerization initiator such as camphoroquinone and a polymerizable promoter such as methacrylic acid. Polymerizable promoters within the scope of the present invention have at least one ethylenically unsaturated group and at least one carboxylic acid group. The primer may further comprise a solvent such as ethanol, a natural resin such as Canadian balsam and a polymerizable resin such as 2-hydroxyethyl methacrylate (HEMA). The primer can also be formed from a mixture of a polymerization initiator, a natural resin and a polymerizable resin.
