Estimating the term…
A resin composition comprises (1) a thermoplastic resin and (2) a modified polyacetal wherein a residue of a polymerizable compound having a functional group such as an epoxy group, a carboxyl group, an acid anhydride group or others is introduced to a base polyacetal in a proportion of 0.1 to 30% by weight relative to the base polyacetal. The thermoplastic resin includes various polymers such as an olefinic polymer, a styrenic polymer, a polyester, a polyamide and so on. The thermoplastic resins can be used singly or in combination, and the latter combination includes a combination of two or more species of resins being immiscible with each other, a combination of a polyacetal and a resin except for a polyacetal (e.g. an elastomer, etc.) and other combinations. The relative ratio of (1) the thermoplastic resin to (2) the modified polyacetal is such that the former/the latter equals about 1/99 through 99/1 (by weight).
A thermoplastic resin composition which comprises (1) at least one thermoplastic resin and (2) a modified polyacetal which is introduced, to a base polyacetal, with a residue of a polymerizable compound having at least one functional group selected from the group consisting of an epoxy group, a carboxyl group, an acid anhydride group, an ester group, an ether group, an amide group, an amino group, a nitrile group, an isocyanate group, an imide group, a cycloalkyl group, an aryl group and a heterocyclic group containing a nitrogen atom as a hetero atom.
A thermoplastic resin composition which comprises;
A thermoplastic resin composition which comprises (I) a modified polymer composition containing (1c) a modified polymer which is a thermoplastic resin selected from the group consisting of an olefinic polymer, a diene polymer, an acrylic polymer, a styrenic polymer, a vinyl polymer, a polyether, a poly(phenylene ether), a polysulfone, a poly(ether sulfone), a poly(ether imide) and a poly(amide imide), and said thermoplastic resin is introduced with at least one functional group selected from the group consisting of an epoxy group, a carboxyl group, an acid anhydride group, an ester group, an ether group, an amide group, an amino group, an imide group, an isocyanate group and a heterocyclic group containing a nitrogen atom as a hetero atom, and (II) a modified polyacetal resin composition containing (2) a modified polyacetal which is introduced, to a base polyacetal, with a residue of a polymerizable compound having at least one functional group selected from the group consisting of an epoxy group, a carboxyl group, an acid anhydride group, an ester group, an ether group, an amide group, an amino group, a nitrile group, an isocyanate group, an imide group, a cycloalkyl group, an aryl group and a heterocyclic group containing a nitrogen atom as a hetero atom.
A thermoplastic resin composition which comprises (1a) a polyacetal, (1e) an elastomer and (2a) a modified polyacetal being introduced with an epoxy group to a base polyacetal.
A method of producing a thermoplastic resin composition which comprises mixing (1) at least one thermoplastic resin and (2) a modified polyacetal which is introduced, to a base polyacetal, with a residue of a polymerizable compound having at least one functional group selected from the group consisting of an epoxy group, a carboxyl group, an acid anhydride group, an ester group, an ether group, an amide group, an amino group, a nitrite group, an isocyanate group, an imide group, a cycloalkyl group, an aryl group and a heterocyclic group having a nitrogen atom as a hetero atom.
