Abstract
A process for the manufacturing of copoly mers of aldehydes, vinyl ethers, and certain copolymers of aldehydes and vinyl ethers can be performed. The copolymerisation is carried out in the presence of at least one reactive boron trihalide complex, and optionally, in the presence of at least one Bronsted Acid and/or Lewis Base.
Claims20
A process, comprising:
- copolymerising at least one vinyl ether (V) and at least one aldehyde (A), optionally in the presence of at least one solvent,
- wherein the copolymerisation is carried out in the presence of at least one reactive boron trihalide complex of the formula
- BX3×x ROH
- wherein
- X is a halide,
- ROH is an alcohol or water, and
- x is a positive number of more than 0(zero),
- optionally in the presence of at least one Brønsted Acid (BA) and/or Lewis Base (LB), wherein a molar ratio of the at least one vinyl ether (V):the at least one aldehyde (A) is from 10:1 to 1:1.
5 more elements
A copolymer, comprising:
- a polymerised form of at least one vinyl ether (V) and at least one aldehyde (A), wherein the at least one aldehyde (A) is an aliphatic aldehyde, wherein a molar incorporation ratio of the at least one vinyl ether (V):the at least one aldehyde (A) is from 10:1 to 1:1.
A copolymer, comprising:
- a polymerised form of at least one vinyl ether (V) and at least one aldehyde (A), wherein the at least one vinyl ether (V) is a C5- to C12-cycloalkyl vinyl ether, wherein a molar incorporation ratio of the at least one vinyl ether (V):the at least one aldehyde (A) is from 10:1 to 1:1.
A copolymer, comprising:
- a polymerised form of at least one vinyl ether (V) and at least one aldehyde (A), wherein the at least one vinyl ether (V) is at least one selected from the group consisting of C10- to C20-alkyl vinyl ethers and C10- to C20-alkenyl vinyl ethers, wherein a molar incorporation ratio of the at least one vinyl ether (V):the at least one aldehyde (A) is from 10:1 to 1:1.
