Method for obtaining a polymer-reinforced composite based on natural polymers containing hydroxyapatite

摘要

the subject of the invention is a composite of the polymer chain receive based on natural polymers, containing hydroxyapatite, intended for medical applications as biomateriau0142 implantacyjny. how is that a suspension of (a) the hydroxyapatite natural or synthetic, grain size below 200 mm, in quantities of 1 to 60 wt%.in aqueous acrylic acid neutralised positively sensitive potassium hydroxide, at a concentration of 10 to 50%, which is the process of ultrasonic homogenization at 20 to 90u00b0c in time from 1 to 20 minutes, after which the suspension (a) distributes during mixing: water roztw u00f3r (b) natural polymer at concentrations from 1 to 60% by weight, of 1 to 50% by weight.in relation to the suspension (a), then the aqueous solution polymerization initiator (c) at a concentration of 1 to 30 wt%. in such a quantity that the mass initiator groups - cooh acrylic acid ranged between 1: 20 to 10: 1, and next, the aqueous solution (d) factor sieciuju0105cego, at concentrations from 1% to 20% by weight.in such quantities that the ratio factor sieciuju0105cego groups - cooh acrylic acid was in the range from 1: 10 to 20: 1, at the end of the mixture is subjected to homogenization and ultrasonic action field microwave radiation.
