Store the tissue on the chuck if sections are to be cut in the immediate future if not, wrap the tissue in aluminum foil, and place it in a small seal-able plastic bag. Store at -70°C or in the vapor phase of a liquid nitrogen freezer (see Note 6). 

Thermoset polymers are considered to be nonrecycl-able plastic materials. Once they are formed into a... 

This degradation reaction, supplemented by various subsequent oxidation steps, has found renewed interest in the form of the introduction of photodegrad-able plastics as part of the campaign to reduce plastic litter from throwaway packaging. Although as yet there has been no demand for photodegradable mb-bers, the incorporation of a small percentage of a vinyl ketone into a rubber copolymer or homopolymer would open the way to a useful synthesis of block copolymers. 

Starting during 1951 new ablative plastics were developed in Materials Laboratory, WPAFB they are materials that absorbs heat, while part of... 

It is apparent, then, that the performance of an ablative plastic is achieved in a manner quite unlike that for heat-resistant plastics. Ablators depend upon various degradative reactions to absorb, dissipate, and block a copious amount of heat. On the contrary, heat-resistant plastics must essentially remain intact during high temperature exposure to retain a significant fraction of their room-temperature properties.
