摘要:
The present invention is related to a linear functional polymer having repeating units A, B and D. Unit A represents —CH2—, unit B represents and unit D represents where R1 represents a polar functional group. There are at least four A units separating each B unit, each D unit, and each B and D unit. The value y represents the total number of B units and is an integer greater than or equal to 1. The total number of D units is represented by h and is an integer greater than or equal to 0. And x represents the total number of A units and is an integer sufficient that the molar fraction of the B and D units in the linear functional polymer is represented by a value j defined by the equation: j = y + h x + y + h ≤ 0.032 . The present invention is also directed to a method for preparing such linear functional polymers by copolymerizing a first polar substituted monomer and a second non-polar unsubstituted monomer.

摘要:
Improved CO2 sorbents comprised of a mesoporous silica functionalized with a polyamine are obtained by the in-situ polymerization of azetidine. Also included herein are processes utilizing the improved CO2 sorbents wherein CO2 is chemisorbed onto the polyamine portion of the sorbent and the process is thermally reversible.
