Abstract
Monomers containing sterically available vinyl groups can be copolymerized with wool in the presence of a mineral acid or an organic acid containing up to 3 carbon atoms. The effect can be enhanced by conducting the reaction in the presence of an activating radiation.
Claims9
A method of grafting a (monomeric substance) vinyl monomer containing sterically available vinyl group onto wool (comprising) consisting of contacting the wool with (the monomer or) a solution (of the monomer) containing at least 30% by weight monomer based on the total weight of the solution in a polar solvent in the presence of a single chemical catalyst, said chemical catalyst being (a mineral acid or an organic acid containing up to 3 carbon atoms) nitric acid, the acid being present in an amount such that the reaction mixture is not more than 0.5N relative to said acid.
