Abstract

Carbamate and thiocarbamate compounds are described that comprise a polymerizable moiety and one or more free hydroxyl and/or thiol groups. Polymers may be obtained by polymerizing these carbamate and/or thiocarbamate compounds. The carbamate and thiocarbamate compounds, as well as the polymers they produce may be formulated into adhesive, agricultural, biocide, cleaning, coating, encapsulation, membrane, oilfield, performance chemical, and personal care compositions.

Claims (4)

1. A polymer represented by one of the structures:

wherein R 1 is hydrogen or methyl; a, b, c, d, and e are molar percentages, wherein each molar percentage ranges from 0.001 mole percent to about 99.999 mole percent, and wherein the sum of the molar percentages is 100 mole percent.

2. A composition comprising a polymer represented by one of the structures:

wherein R 1 is hydrogen or methyl; a, b, c, d, and e are molar percentages; wherein each molar percentage ranges from 0.001 mole percent to about 99.999 mole percent, and wherein the sum of the molar percentages is 100 mole percent.
