Carbamate-functional resins having improved adhesion, method of making the same, and method of improving intercoat adhesion

A method of making a carbamate-functional polymer, comprising

• preparing a backbone polymer comprising one or more functional groups F′ by addition polymerizing
• from at least 66 to 100% by weight, based on the total weight of the carbamate-functional polymer, of one or more ethylenically unsaturated carbamate free monomers A having at least one functional group F′, and
• from 0 to less than 35% by weight, based on the total weight of the carbamate-functional polymer, of one or more nonfunctional ethylenically unsaturated monomers A′, and
• reacting the backbone polymer with one or more compounds B so as to produce a carbamate-functional polymer having at least one carbamate group, said one or more compounds B having at least one functional group (b1), which upon reaction with either a functional group F′ or the reaction product of one or more prior reactions of a functional group (b1) and functional group F′, results in a carbamate group,
• wherein the carbamate-functional polymer having at least one carbamate group has an equivalent weight of at least 250 grams of polymer per carbamate group.

A method of making a composite comprising a coated substrate, an adhesive composition, and a glass having at least one surface, the method comprising

• providing a coating composition comprising a polymer having a backbone resulting from addition polymerization and from 0 to less than 35 weight percent of repeat units from nonfunctional ethylenically unsaturated monomers A′, based on the total weight of the polymer,
• applying the coating composition to a substrate to provide a coated substrate,
• applying an adhesive composition to the coated substrate, and
• adhering a glass having at least one surface to the adhesive composition to form a composite wherein the at least one surface of the glass is adhered to the coated substrate by the adhesive composition.
