摘要:
The object of the present invention is the production of thermoplastically workable copolymers capable of being composted, characterized in that they consist of partially crystalline soft segments formed from aliphatic esters and also of amorphous hard segments and that the proportion of soft segments amounts to 70% to 95% by weight.

A method of foaming thermoplastic aromatic polycarbonates is disclosed. Accordingly, a polycarbonate resin is mixed with 0.01 to 10%, the percent being relative to the total weight of polycarbonate resin and polysaccharide, of a particular polysaccharide and the mixture then processed thermoplastically without the application of negative pressure in an extruder, at temperatures of 180.degree. C. to 320.degree. C., or in an injection molding machine, at temperatures of 190.degree. C. to 330.degree. C., to obtain foamed molded articles.

摘要:
Methods of protecting a crop from weed infestation, controlling weed growth, reducing fumigant dosage in crop protection, and reducing the growth of weeds by applying a polymer composite material with or without a biocide to soil, a crop, a vegetable, a weed, or combinations thereof are provided. In an aspect, the disclosure provides for a polymer composite material including a base polymer coated with: (1) a first barrier layer; (2) a second layer with our without a biocide; and (3) a third protective layer.
摘要:
Polymer composite material with barrier functionality, in particular for the use in fumigation methods, comprising at least one base polymer compound and at least one barrier functional layer, wherein the barrier functional layer comprises at least one binder that is cross-linkable and after cross-linking capable of water absorbing and gel-forming.
