Abstract: Polymers are prepared from a vinyl monomer or monomers by a homopolymerization or a copolymerization reaction which occurs exothermically, said reaction being carried out by mixing the vinyl monomer or monomers with an additive comprising an endothermic compound which is unreactive with said monomer or monomers and the resultant homopolymers or copolymers and has a phase transition point at the temperature of the polymerization reaction with the absorption of heat, the amount of said endothermic compound being sufficient to counterbalance the major part of the exothermic heat of reaction, the process being especially useful for preparing polymers in solid form or for preparing high solid suspensions of polymers.

Abstract: A composite piece 9 comprises at least two layers 3,5 of flexible materials which may be identical or different. Adjacent layers 3,5 are bonded by multiplicities of interposed thermoplastic beads 7 which lie equally spaced along parallel lines and adhere to both adjacent layers. The piece 9 may be made by passing layers 3,5 and an interposed thermoplastic (preferably high-density polyethylene) lattice having the form of beads linked by thin threads through a heated calendar 1,2, whereby the threads are melted away and the beads 7 heat-welded to the layers 3,5. One or both external faces may be dyed or printed simultaneously with the head-welding step by including transfer paper(s) 11,12 in the "sandwich" passed through the calendar.The composite pieces 9 may be applicable to e.g., furnishings and clothing, and especially to reversible garments.
