Abstract: PROBLEM TO BE SOLVED: To obtain the subject copolymer having a rapid hardening rate, manifesting high hardness, water resistance, chemical resistance or the like and useful for uses such as a coating material by allowing the copolymer to include a specified 5-membered cyclic dithiocarbonate group and a specific group. SOLUTION: The objective copolymer contains a 5-membered cyclic dithiocarbonate group of formula I (R to R are each H or a lower alkyl) and a group of formula II (R to R are each H, an alkyl, an aralkyl, a halogen, an alkoxy, an amino or the like). The copolymer is obtained, for example, by copolymerizing (A) 0.1-50 wt.% vinyl-based monomer having the group of formula I, (B) 0.1-30 wt.% vinyl-based monomer having the group of formula II and (C) a vinyl-based monomer copolymerizable with these monomers. The component A is preferably a monomer of formula III [R is H, methy] or ethyl; (n) is 1-6]. Preferably, γ-methacryloxypropyltrimethoxysilane or the like is used as the component B.

Abstract: PROBLEM TO BE SOLVED: To obtain a composition which hardly emits a sulfur-like odor and is excellent in hardness, strengths, adhesiveness, and resistances to water, chemicals, weather, staining, blocking, or the like, by compounding a compound or polymer having at least one 5-memebered cyclic dithiocarbonate group, a nucleophilic reagent, and a metal phthalocyanine (salt). SOLUTION: A polymer or compound having at least one 5-membered cyclic dithiocarbonate group represented by formula I, a nucleophilic reagent, and 0.0001-10 wt.% metal phthalocyanine (salt) represented by formula II are compounded. In the formulas, R1 to R3 are each H or a lower alkyl; X is a metal atom; and Y1 to Y16 are each H, an alkyl, a substituted alkyl, a halogen, nitro, amino, azo, thiocyanate, carboxyl, a haloformly, formyl, carbamoyl, cyano, hydroxyl, an alkoxy, an aryloxy, or the like. The nucleophilic reagent is the one which gives a share in electrons to the thiocarbonyl group of the 5-membered cyclic dithiocarbonate group, and its example is a compound having an amino, hydroxyl, imino or thiol group.
