Abstract:
A method of making a carbamate-functional polymer, comprisingpreparing a backbone polymer comprising one or more functional groups Fâ€² 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 Fâ€², 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 Aâ€², 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 Fâ€² or the reaction product of one or more prior reactions of a functional group (b1) and functional group Fâ€², 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.
