Abstract:
A process for preparing an oligomer, a cooligomer, a polymer or a copolymer (block or random) by free radical polymerization of at least one ethylenically unsaturated monomer or oligomer, which process consists ofheating and polymerizing the monomer, monomers, oligomer or oligomers in the presence of a free radical source and at least one compound of formula (I) â€ƒwhere n is 1 or 2; R3, R4, R9, R10 are each independently of one another C1-C18alkyl, C2-C18alkenyl or C2-C18alkinyl; or R3 and R4 and/or R9 and R10 form together with the linking carbon atom a C3-C12cycloalkyl radical; R5, R6, R7, R8 are each independently of one another hydrogen, C1-C18alkyl, C2-C18alkenyl or C2-C18alkinyl; X is â€”Oâ€”, â€”Oâ€”C(O)â€”, â€”NR2â€” or â€”NR2â€”C(O)â€”; R2 is hydrogen, C1-C18alkyl or phenyl; if n is 1, R1 is C8-C36alkyl, C8-C36alkenyl or C8-C36alkinyl; and if n is 2, R1 is C10-C36alkylene, C10-C36alkenylene or C10-C36alkinylene.
