  • Process for the preparation of grafted polymers of .alpha.-substituted-.beta.-propiolactone on amorphous base polymers
    Patent number: 4282338
    Abstract: A method is disclosed for preparing graft polymers of alpha-substituted-beta-propiolactones, comprising the step of providing anionic sites in an amorphous base polymer and reacting the anionic compound with an alpha-substituted-beta-propiolactone. Critical concentrations of unsaturation in the base polymer and critical quantities of the beta-propiolactone concerned are indicated.

  • Polycondensation thermoplastic elastomers composed by alternatingly arranged copolyesteramides
    Patent number: 4105640
    Abstract: Novel thermoplastic elastomers are disclosed, which are based on copolyesteramides and are composed by a statistically distributed array of soft and hard molecular chains, bonded to each other by ester bonds. These thermoplastic elastomers have shown an improved resistance to heat and hydrocarbonaceous fluids such as fuels, lubricants and the like.
