Abstract
(EN) A degradable polymer composite comprises a polyurethane comprising one or more of the following groups: ester groups; carbonate groups; or ether groups, in a backbone of the polyurethane; and about 1 to about 30 parts by weight of an acidic or basic powder comprising particles having an average size of about 5 microns to about 1 millimeter per 100 parts of the polyurethane.
(FR) La présente invention concerne un composite polymère dégradable comprenant un polyuréthane comprenant un ou plusieurs des groupes suivants : des groupes ester ; des groupes carbonate ; ou des groupes éther, dans un squelette du polyuréthane ; et environ de 1 à environ 30 parties en poids d’une poudre acide ou basique comprenant des particules ayant une taille moyenne d’environ 5 microns à environ 1 millimètre pour 100 parties du polyuréthane.
