Abstract
(EN)
The purpose of the present invention is to provide a polyacetal resin composition which has improved mechanical properties. The present invention has been achieved by a polyacetal resin composition which is obtained by mixing 0.1-100 parts by mass of a polyacetal copolymer (B) with 100 parts by mass of a polyacetal resin (A), said polyacetal copolymer (B) being obtained by copolymerizing at least a trioxane (a) and a compound (b) which has an alkoxysilyl group and at least one trioxane copolymerizable functional group that is selected from among epoxy groups and cyclic acetal groups, with the trioxane copolymerizable functional group and the alkoxysilyl group being bonded only by a bond chain that is selected from among a carbon-carbon bond and an ether bond.

La présente invention a pour objet une composition de résine de polyacétal qui comprend des propriétés mécaniques améliorées. La présente invention a été obtenue par une composition de résine de polyacétal qui est obtenue par mélange de 0,1 à 100 parties en masse d'un copolymère de polyacétal (B) avec 100 parties en masse d'une résine de polyacétal (A), ledit copolymère de polyacétal (B) étant obtenu par copolymérisation d'au moins un trioxane (a) et d'un composé (b) qui comprend un groupe alcoxysilyle et au moins un groupe fonctionnel copolymérisable avec le trioxane qui est choisi parmi des groupes époxy et des groupes acétal cyclique, le groupe fonctionnel copolymérisable avec le trioxane et le groupe alcoxysilyle étant liés uniquement par une chaîne de liaison qui est choisie parmi une liaison carbone-carbone et une liaison éther.
