Abstract

A method for producing a system, a solid diffuser releasing vapors of air odor improving agents, provided with a polymeric matrix, the method of which comprises a polymerization, in which said agent is introduced before the step of forming said matrix, characterized in that 5 to 95% by weight of a monomeric reagent, which consists of (A) one or more monomers that provide olefinically polyunsaturated hydrophobic polymers, which are rapidly polymerizable and crosslinkable by radical polymerization, each monomer comprising per molecule, therefore minus two terminal groups of the formula **(See formula)** where Y represents one of the groupings **(See formula)** m and n each represent 1 or 2, X represents one of the bridging members (see formula) where p is 1 or 2, **(See formula)** wherein the bond is attached to a carbon atom or a nitrogen atom, the latter preferably being an amino-nitrogen; and when X is the above benzene nucleus, it may be a common bridge member of two to three groups **(See formula)** R represents a hydrogen atom or an organic group free of static hindrance against polymerization O well (B) at least one of the monomers defined in (A) and an olefinically monounsaturated monomer offering hydrophobic polymer rapidly copolymerizable therewith, in a molar% ratio of between 7:93 and 93: 7; O well (c) a monomer as defined in (A) and a monolimeriable with it, in a molar% ratio of between 50:50 and 95:55; is polymerized by radical polymerization, in the presence, in the reaction mixture, of 95 to% by weight of a volatile and nonaqueous air odor improving agent, substantially not copolymerizable with the aforementioned monomers within the time required to form said matrix polymeric, lasts based on percentage weight on combined weight of monomer and agent, whereby a mechanically stable, heat and freeze resistant and syneresis free composition of a solvent insoluble polymeric crosslinker with high odorant trapping capacity is obtained, said odor improving agent entrapped in said crosslinker being comprised.
