    摘要: Copolymers essentially composed of a major portion of monomeric units derived from one or more monomers which are free from ethylenic unsaturation, have at least three carbon atoms and have a polymerizable thiiranyl group; and a minor portion of monomeric units derived from one or more monomers having both a polymerizable thiiranyl group and a polymerizable ethylenically unsaturated group are disclosed. The monomers free from ethylenic unsaturation may be, for example, ethylene sulfide, propylene sulfide, the 1,2- and 2,3-butylene sulfides, vinyl cyclohexane sulfide, 2-benzyl thiirane, paramethyl styrene episulfide, styrene sulfide, cyclohexene episulfide, and isobutylene sulfide. The ethylenically unsaturated monomers may be, for example, allylthioglycidyl ether, thioglycidyl acrylates, thioglycidyl alkacrylates such as thioglycidyl methacrylate, vinyl cyclohexene episulfide, and butadiene monoepisulfide. The monomers are polymerized through the thiiranyl groups thereof. The copolymers can be cured through the ethylenically unsaturated groups thereof to produce elastomers having good physical properties and solvent resistance.

    摘要: GRAFT COPOLYMERS ARE FORMED BY REACTING A NATURALLY OCCURING POLYHYDROXY BASE POLYMER, SUCH AS CELLULOSE, WITH AN N-3-OXOHYDROCARBON-SUBSTITUTED ACRYLAMIDE SUCH AS DIACETONE ACRYLAMIDE IN THE PRESENCE OF A FREE RADICAL CATALYST, PREFERABLY A SALT OF PERIODIC ACID OR A CERIC SALT. THE GRAFTING OPERATION MODIFIES THE PROPERTIES OF THE BASE POLYMER.
