Title:
主にホルムアミドから構成されるポリマーの製造方法
Document Type and Number:
Japanese Patent JP2007536419
Kind Code:
A
Abstract:
The invention relates to a process for the preparation of polymers composed predominantly of vinylformamide and having a low residual vinylformamide monomer content by subjecting (a) 49.9-99.9% by weight of N-vinylformamide, (b) 0-50% by weight of one or more monomers capable of free radical polymerization, (c) 0.1-5% by weight of at least one monomer from the group consisting of N-vinylpyrrolidone, N-vinyl-N-methylacetamide, N-vinylcaprolactam and N-vinylpiperidone to free radical polymerization, the monomer (c) being added to the polymerization only when the proportion of still unpolymerized monomer (a) is <5% by weight.
