Novel oligomers derived from polyethoxylated aliphatic amines, their preparation and use as polymer surface property modifiers

摘要

Oligomer of formula: …IMAGE… where: R1 = H or CH3, R2 = CtH2t with 0 /= t /= 18, Z is chosen from …IMAGE… with 2 /= d /= 16, m is an integer such that 1 /= m /= 3, R3 = Ct'H2t'+1 with t' /= 1 and 8 /= t + t' + 2m /= 22, n and n' are identical or different integers such that 2 /= n + n' /= 20, b is an integer equal to 0 or 1, a is an integer varying between 2 and 500. …??The oligomers obtained by polymerisation of a monomer resulting from the condensation or addition of a polyethoxylated fatty amine or of a mixture of polyethoxylated fatty amines to a monomer containing acrylic unsaturation. The oligomer can be employed as antifogging agent in thermoplastic polymer films.
