No matter how far Humanity advanced in its successes the problems of health and death will always exist. However, it is possible to postpone old age and prolong life, and it is performed successfully. In ancient Rome the average age was 15-18 years. Today in Japan it reaches 77-79 years. So what can the science of polymers do in solving this problem? Do high molecular compounds (natural and artificial) possess any reserves for solving this problem? This book discusses the problems of the polymer interaction with biologically active and model media, biodegradation biodetrioration, prognosing the time of reliable exploitation of polymers for medical purposes, polymer application in surgery, etc. Also discussed is the role of kinetics in prognosis of agriculture production quality.
