Abstract
Method for producing polymers comprises connecting polymeric molecules at least one of which contains tertiary amino groups chemically bound in the chain in the presence of materials such as elemental halogens, compounds of the elements of groups 3 through 8 of the Periodic Table containing one or more halogen atoms or halogen containing organic compounds. It is possible to connect chains of identical or different types and in this way increase the molecular weight, produce block copolymers, cure films and varnishes and perform vulcanization and the like at ambient temperature.
Claims11
A process for forming polymer gel by chemically connecting at least two polymeric molecules each of which contains at least one chemically bound tertiary amino group and which polymeric molecules are polymers and copolymers selected from the group consisting of poly (dimethylaminoethyl) methacrylate and poly (dimethylaminoethyl) acrylate, comprising the steps of mixing said polymeric molecules together, contacting the mixture with a material selected from the group consisting of elemental halogens, halogen containing organic compounds and inorganic halogen compounds of the elements of the third, fourth, fifth, sixth, seventh and eighth groups of the Periodic Table in an amount and for a time sufficient to cause substantially complete reaction of the tertiary amino groups in the mixture of polymeric molecules with said contacting material to form a connected polymeric product and thereafter recovering said product.
